실험 절차

Methylmagnesium bromide (3M solution in diethylether, 51.6 ml, 155 mmol) was slowly added to a solution of 1-(3-bromo-phenyl)propan-2-one (15.0 g, 70 mmol) in dry diethylether (200 ml) at 0° C. The resulting mixture was left for 3 hours, then cooled to 0° C. and slowly quenched with saturated aqueous ammonium chloride solution. The organic phase was washed with brine, dried (sodium sulfate). The yellow oil was then purified by column chromatography on silica gel eluting with dichloromethane:pentane:methanol (90:5:5 by volume to afford a pale yellow oil (13.26 g).
