A mixture of 523 mg (0.41 mmol) of ethyl 3-(1-{l-[(4-chlorophenyl)(3-cyanophenyl)methyl] azetidin-3-yl}-2-fluoro-2-methylpropyl)-5-fluorobenzoate (Preparation 17), 0.6 mL(1 6.36 mmol) of hydrazine, and 4 mL of EtOH was heated to reflux. After 8 h, the mixture was concentrated to remove solvents to afford the of title compound as an white solid. 1H-NMR(CDCl3) δ 1.20(d, 3H, J=21 Hz), 1.29(d, 3H, J=21 Hz), 2.32 (t, 3H, J=7.1 Hz), 2.85 (t, 1H, J=8 Hz), 2.94 (m, 1H), 3.06 (m, 1H), 3.20 (m, 1H), 3.51 (s, 2H), 3.63 (t, 1H, J=5 Hz), 4.26 (s, 1H), 7.06-7.71 (m, 11H); Mass Spectrum: m/e=509 (M+1, 35Cl), 511 (M+1, 37Cl).
