A solution of 1.0 M lithium aluminum hydride (200 ml, 0.2 mole) in tetrahydrofuran was added dropwise to a solution of 1-methanesulfonylpiperidine-4-carboxylic acid ethyl ester (68 grams, 0.29 mole) in tetrahydrofuran (500 ml) at about +5° C. The reaction mixture was stirred at 5-10° C. for 15 minutes. Water (10 ml) was added dropwise and the mixture was filtered. The filtrate was concentrated under reduced pressure and triturated with 50% ethyl ether-hexane (100 ml). The resulting white solid was collected and dried to give 1-methanesulfonylpiperidine-4-methanol (46 grams, 82%), m.p. 96-97° C.
