Dimethylformamide → 2-Isopropyl-6-methylbenzaldehyde

Participants

Reaction Steps

To a solution of 1-bromo-2-isopropyl-6-methylbenzene (6.9 g, 32.4 mmol) in diethyl ether (50 ml) was added magnesium turnings (0.9 g, 37 mmol) and the mixture was refluxed in nitrogen atmosphere until the reaction was started and was then stirred overnight at room temperature. Dimethylformamide (4 ml) was added dropwise during 10 min. and the mixture was stirred for 30 min. Saturated ammmoniumchloride solution (30 ml) was added and the mixture was stirred for 1 h. The organic layer was separated, filtrated and evaporated under reduced pressure. Purification by column chromatography on silica gel using hexane:methylene chloride (3:2) as eluent gave 1.75 g (33%) of the title compound .
