Reaction Steps

To a solution of 175 mg (0.368 mmol) of 1-{1-[bis(4-chlorophenyl)methyl]azetidin-3-yl}-1-(3,5-difluorophenyl)-2-methylpropan-2-ol in 3 mL of CH2Cl2, 1 mL of hydrogen fluoride-pyridine was added and the reaction was stirred for 9 h at 42° C. Then the reaction mixture was poured to 7 mL of 5N NaOH, 7 mL of ag NaHCO3 and 30 mL of CH2Cl2. Adjusted pH to 8-9 with 2N NaOH. The water layer was extracted with CH2Cl2 (3×30 mL). The combined organic layer was dried over Na2SO4 and concentrated. The residue was purified by silica gel chromatography with 10% methyl tert-butyl ether-hexane to afford the title compound as a white solid. 1H NMR(CDCl3) δ 1.25 (t, J=22 Hz, 6H), 2.33 (t, J=6.5 Hz, 1H), 2.83-2.89 (m, 2H), 3.09-3.11 (m, 2H), 3.60 (m, 1H), 4.20 (s, 1H), 6.68-6.71 (m, 3H), 7.21-7.33 (m, 8H)
