Procedure

To a solution of 805 mg (1.81 mmol) of {1-[bis(4-chlorophenyl)methyl]azetidin-3-ylidene}(3,5-difluorophenyl)acetaldehyde in 20 mL of THF was added slowly a solution of 1.33 mL (4.0 mmol) of methylmagnesium chloride (3.0M solution in THF) at −78° C. and stirred for 1 h. The reaction mixture was warmed to 0° C. for 1 h and 3 g of sodium sulfate decahydrate was added to quench the reaction, followed by stirring for 1 h at rt. The quenched reaction mixture was filtered and the organic layer was dried over Na2SO4 and concentrated. The residue was purified by silica gel chromatography with hexanes/acetone=8:1 to afford {1-[bis(4-chlorophenyl)methyl]azetidin-3-ylidene}-1-(3,5-difluorophenyl)propan-2-ol as a white solid. Mass Spectrum m/e=460 (M+1 35Cl, 35Cl) and 462 (M+1 35Cl, 37Cl).
