실험 절차

A stirred solution of 76.1 g of methyl 1-benzyl-4-anilino-4-piperidine carboxylate in 1200 ml of toluene is maintained at ambient temperature while 130 ml of a 70% solution of sodium dihydrobis(2-methoxyethoxy)aluminate in benzene is added dropwise. Stirring is continued for one hour after the addition. Two hundred grams of a saturated solution of sodium sulfate is added. The aqueous portion is removed and the organic portion is dried over sodium sulfate and flash evaporated to give 72.5 g of 1-benzyl-4-anilino-4-piperidinemethanol, as an oil.
