Following a procedure similar to that described in Example 38(a), 1.00 g of (R)-1-t-butoxycarbonyl-2-{2-[2-(3-methoxyphenyl)ethyl]phenoxymethyl}pyrrolidine [prepared as described in Example 76(a)] was reacted with 0.184 g of lithium aluminum hydride dispersed in 10 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 20:1 by volume mixture of methylene chloride and methanol as the eluent, to give 0.750 g (yield 95%) of the title compound as a colorless oil.
