실험 절차
Methylmagnesium bromide (3.6 mL, 10.67 mmol, Aldrich, 3 M solution in ether) was added to a cooled (−10° C.) solution of 3-chloroacetophenone (1.5 g, 9.7 mmol) in anhydrous ether slowly over 30 min. After complete addition, the reaction mixture was slowly warmed to room temperature, stirred for 18 hours. Again cooled (−5° C.), than quenched with sat. ammonium chloride solution over 30 min. The reaction mixture was extracted with ether, dried, filtered and concentrated to afford 1.55 g of 2-(3-chlorophenyl)propan-2-ol.
