Procedure

To a slurry of LiAlH4 (4 equivalents) in dry THF, cooled to 0° C. under N2, was slowly added drop-wise a solution of methyl 4-[4-(1-BOC-piperazin-4-yl)phenoxymethyl]benzoate (1 equivalent) in dry THF. Once the addition was complete, the slurry was heated to reflux at 80° C. for 1 hour. The slurry was subsequently cooled to 0° C. and treated with water, 10% aq. NaOH and with water again. The resulting solids were filtered, and the filtrate was diluted with chloroform, washed with brine, dried over MgSO4 and concentrated, providing the crude 4-[4-(4-methylpiperazin-1-yl)phenoxymethyl]benzyl alcohol which was used without purification.
