To a stirred solution of tert-butyl 2-(1-(4-bromophenyl)piperidin-4-yloxy)acetate (3.08 g, 8.3 mmol) in THF (20 mL) at −10° C. under nitrogen was added lithium aluminum hydride (0.57 g, 15 mmol). After 2 hours, the reaction mixture was quenched by sequential addition of water (0.6 mL), 15 percent aqueous sodium hydroxide solution (1.8 mL) and water (0.6 mL). The resulting mixture was filtered and concentrated under vacuum to provide the crude 2-(1-(4-bromophenyl) piperidin-4-yloxy)ethanol 2.16 g. MS (m/z): 302 (M+2)+
