실험 절차
Following a procedure similar to that described in Example 38, 850 mg of 1-t-butoxycarbonyl-3-{2-[2-(3-methoxyphenyl) ethyl]phenoxymethyl}piperidine (prepared as described in Example 49) were reacted with 113 mg of lithium aluminum hydride. The mixture was then worked up as described in Example 38, and the crude product thus obtained was purified by column chromatography through silica gel, using a 10:1 by volume mixture of methylene chloride and methanol as the eluent, to give 520 mg (yield 76%) of the title compound as a solid.
