To a solution of 1-{3-[5-bromo-2-(5-trifluoromethyl-furan-2-ylmethoxy)-benzyl]-azetidin-1-yl}-2,2,2-trifluoro-ethanone (76 mg, 0.16 mmol) in methanol (10 mL) was added K2CO3 (94 mg, 0.70 mmol). After 1 h, TLC analysis indicated complete consumption of the starting material. Brine and EtOAc were added to the reaction mixture and the aqueous portion was extracted with EtOAc (3×). The combined organic layers were dried. The crude product was purified by RP HPLC (basic conditions) to provide the title compound (50 mg, 76%). MS (ESI): mass calcd. for C16H15BrF3NO2, 390.2; m/z found, 393.2 [M+H]+. 1H NMR (CDCl3): 7.50-7.41 (m, 1H), 7.35-7.26 (m, 1H), 6.89-6.79 (m, 2H), 6.53 (s, 1H), 5.05 (s, 2H), 4.43-4.20 (m, 1H), 3.63 (t, J=8.2 Hz, 2H), 3.44 (t, J=7.7 Hz, 2H), 2.85 (d, J=7.6 Hz, 2H).
