47% | Step 1: A solution of <strong>[100189-84-2]2,5-dibromoxylene</strong> (2.0 g, 7.6 mmol) in DCM (20 ml) was treated with n-BuLi (2.5 M solution in hexane, 3 ml, 1.0 equiv.) at -78C. After stirring for 1h, DMF (1.8 ml, 23 mmol, 3 eq.) was added and the solution was allowed to warm to room temperature. It was acidified to pH 2 with 5% hydrochloric acid and extracted with diethyl ether (3x50 ml). The combined organic phase was dried and evaporated and the residue was purified by column chromatography using PE:EA = 10:1 as eluent to give 4-bromo-3,5-dimethylbenzaldehyde (0.76 g, yield: 47%). | |
A solution of <strong>[100189-84-2]2,5-dibromoxylene</strong> (8.0 g, 30.3 mmol) in diethyl ether (120 mL) is cooled to -78 C. and then treated with n-buthyllithium (20 mL, 1.6 M in hexane). After stirring for 40 min, DMF (6 mL) is slowly added. The mixture is warmed to rt and stirred for 1 h. The mixture is cooled again to -78 C. before another portion of n-butyllithium (5 mL) is added. The reaction mixture is allowed to warm to rt and stirred for another hour. The reaction is quenched by adding 5% aq. HCl. The mixture is extracted with EA, and the extract is concentrated in vacuo. The crude product is purified by CC on silica gel eluting with heptane:EA 5:1 to give 4-bromo-3,5-dimethyl-benzaldehyde (8.2 g) as a white soft solid. | ||
