Sloppy Liverpool escape to victory Mohamed Salah's goal was his 184th for Liverpool in 300 appearances dimethylaniline (2 g, 16.5 mmol), and acetonitrile (80 mL) were added to a 25 mL single-mouth bottle, and stirred for 5 min under ice bath, then NBS (3.94 g, 21.6 mmol) was dissolved in acetonitrile (20 mL)), added dropwise to the single-mouth bottle, and after addition, reacted for 2 hours under ice bath. After the reaction, water (50 mL) was added, and the mixture was extracted with ethyl acetate (100 mL33). The organic layers were combined, and concentrated in vacuo to remove the solvent to separate by a silica gel column (petroleum ether: ethyl acetate = 10:1-4:1) to give the product of 4-bromo-3, 5-dimethylaniline (white solid, 2.3 g), with a yield of 69.7%. 1H NMR (400 MHz, CDCl3) delta 6.44 (s, 2H), 3.45 (s, 2H), 2.31 (s, 6H).

First, 3,5-dimethyl aniline (10.0 g, 82.5 mmol) was dissolved in MeCN. NBS (15.4 g, 86.6 mmol) was added and the reaction mixture was stirred for two days at room temperature. Analysis by TLC and HPLC indicated that in addition to the desired product several side products had been formed (regio-isomers and di-brominated side products). Silica gel was added to the reaction mixture and the solvent was evaporated under reduced pressure. The resulting dry crude product was loaded on a chromatography column and purified by eluting with hexanes/ethyl acetate (gradient 0% to 15% ethyl acetate). The product, 4-bromo-3,5-dimethylaniline, was obtained in 50% yield (8.21 g). MS (ES) 200/202 What is 90 Divided by 3 Using Long Division?". VisualFractions.com.

To a solution of 3,5-dimethylaniline (3.0 ml, 24 mmol) in ice cold dichloromethane (200 ml) was added trifluoroacetic anhydride (4.18mL, 1.25 equivs). After 30 minutes, bromine (1.2 ml, 0.97 equivs) was slowly added over 5 minutes. After aqueous work-up and drying in vacuo the recovered crude (6.81 g, 96percent) was taken up in dry THF (40 ml). The solution was cooled to -78 0C and methyl lithium'lithium bromide complex (21 ml, 1.3 equivs) was added. After 5 minutes, s-butyllithium (20 ml, 1.3 equivs) was added followed by di-t-butyldicarbonate (8.02 g, 1.6 equivs). Following aqueous work up the crude amide was taken up in a 3:1 solution of methanol: water (100 ml) followed by sodium hydroxide (5 ml, 1OM, 2 equivs). The reaction was stirred at 6O 0C overnight. Solvent was removed and the crude was diluted with dichloromethane, washed with water, brine, and dried over sodium sulfate. The aniline was then taken up in dichloromethane (2 ml) and n-propylisocyanate (74 μL, 1.2 equivs). After two hours, solvent was removed and the crude residue was taken up in HCl/ethanol solution (1.2M, 15 ml) and stirred at 50 °C overnight. After solvent was removed, the crude 2,6-dimethyl-4-(3- propyl-ureido)-benzoic acid was isolated as a white solid (94 mg).[0425] 1H NMR (CDCl 3) δ 0.83-0.99 (m, 7H), 1.02-1.11 (m, IH), 1.46-1.77 (m, 8H), 2.11 (s, 6H), 2.48-2.57 (m, IH), 1.66-1.82 (m, 3H), 3.12-3.22 (m, 3H), 3.52-3.20 (m, 4H), 3.75-3.82- 3.90 (m, IH), 4.11-4.25 (m, IH), 5.67-5.75 (m, IH), 6.61 (s, 2H), 6.89 (d, IH, J= 6 Hz), 7.03 (s, IH), 7.22 (s, IH), 7.27-7.32 (m, IH), 7.48 (s, IH), 8.87 (br s, IH); ES-MS m/z 573 (M+H).

For x = -9, what is the value of Z, where Z equals fraction numerator x minus 17 over denominator 6.5 end fraction. Give your answer to 2 decimal places. Liverpool are right in the fight for a place in Europe as they overhauled Spurs, but this was a performance that demonstrated once again the two sides to their game they have shown throughout this season. Spurs pay for slow start again Interim manager Ryan Mason will surely have warned his players about the perils of such a hesitant opening and yet they played the opening 15 minutes as if they were in a daze.Please note that the final angular degrees (approx. 2°) before the end position can only be approached using the force of a single drive piston. For this reason, double actuated modules only have about half the rated torque available in this area. An external stop can be used to provide the full torque even in the end positions. To a solution of [59557-90-3]4-bromo-3,5-dimethylaniline (3.47 g, 17.4 mmol) and diisopropylethylamine (5.3 mL, 30.4 mmol) in DMI (13 mL), 2-bromoisobutyric acid (3.86 g, 23.1 mmol) was added at room temperature. The mixture was stirred at 100C for one hour. And then 2-bromoisobutyrate (496 mg, 2.97 mmol) and diisopropylethylamine (0.8 mL, 4.59 mmol) was added and the mixture was stirred at 100C for one hour. Methanol (52 mL) and a 5 N aqueous sodium hydroxide solution (52 mL, 260 mmol) were added to the reaction mixture at room temperature, and then this mixture was stirred at 75C for 1.5 hours. The reaction mixture was cooled, followed by addition of water and adjustment of the pH to 5 using a 1 N aqueous potassium hydrogen sulfate solution, and then extracted using ethyl acetate. The organic layer was washed with water, then dried over anhydrous magnesium sulfate, and concentrated to yield 2-((4-bromo-3,5-dimethylphenyl)amino)-2-methyl propanoic acid as a crude product (5.79 g).
