Procedure

300 mg of 1-benzhydrylazetidin-3-one dissolved in 3.8 ml of tetrahydrofuran was added to 2 ml of 1M cyclopropyl magnesium bromide/tetrahydrofuran solution under ice water cooling, and the mixture was allowed to warm to room temperature and stirred for 30 minutes. The reaction solution was poured into a saturated aqueous solution of sodium carbonate and the mixture was subjected to extraction with diethyl ether, and dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and then the obtained residue was purified by silica gel column chromatography to obtain 334 mg of the objective compound.
