Procedure

To a solution of LiAlH4 (1.8 g, 0.048 mmol) in THF (40 mL) at 0° C. was added dropwise via addition funnel a solution of 2-[4-hydroxy-1-(phenylmethyl)-4-piperidinyl]acetamide (4 g, 0.016 mmol) in THF (40 mL). The solution warmed to 25° C. and was then heated to reflux for 12 h. After cooling, the solution was then carefully quenched with a saturated solution of sodium potassium tartrate and extracted several times with DCM. The combined organic fractions were dried (Na2SO4) and the resulting residue was used directly without further purification: LCMS (ES) m/e 236 (M+H)+.
