Following a procedure similar to that described in Example 38(a), 1.00 g of 1-t-butoxycarbonyl-2-(2-{2-[2-(4-ethylphenyl)ethyl]phenoxy}ethyl)piperidine [prepared as described in Example 69(a)] were reacted with 0.173 g of lithium aluminum hydride dispersed in 20 ml of tetrahydrofuran. The mixture was then worked up as described in Example 38(a), 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 0.650 g (yield 81%) of the title compound as a colorless oil.
