Procedure

A solution of methyl 4-allylbenzoate (5.66 g, 32.1 mmol) in tetrahydrofuran (37 mL) at 0° C. under an argon atmosphere was charged with a solution of methyl magnesium bromide in diethyl ether (3 M, 26.8 mL, 80 mmol). The reaction mixture was allowed to warm to room temperature and then it was cooled to 0° C. after an additional four hours, at which time a saturated aqueous ammonium chloride solution (50 mL) was added slowly followed by diethyl ether (100 mL). The layers were separated, and the aqueous layer was extracted with diethyl ether (2×50 mL). The combined organic layers were dried over magnesium sulfate, filtered, and concentrated to afford the title compound.
