Dimethylformamide → 2-(Propan-2-yl)benzaldehyde

참여 물질

반응 단계

To a solution of 2-bromoisopropyl benzene (2.0 g, 10.0 mmole) in dry THF (20 mL), nBuLi (1.6 M in hexanes) (6.9 mL, 11.05 mmole) was added at −78° C. and the mixture was stirred at same temperature for one hour. DMF (0.9 g, 12.0 mmole) was added and the mixture was stirred at −78° C. for an additional half an hour, then allowed to stir at 0° C. for 15 min. The reaction mixture was diluted with saturated aqueous ammonium chloride (10 mL) and extracted with ethyl acetate (3×30 mL). The combined organic layers were washed with brine and dried over sodium sulfate. The solvent was evaporated to yield 2-isopropyl benzaldehyde (1.4 g).
