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

Participants

Reaction Steps

To a solution of 2-bromoisopropyl benzene (2.0 g, 10.0 mmole) in dry THF (20 mL), nBuLi (1.6 M in hexane), (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 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 EtOAc (3×30 mL). The organic layers were combined and washed with brine, dried over sodium sulfate, and concentrated to yield 2-isopropyl benzaldehyde (1.4 g).
