실험 절차

Following a procedure similar to that described in Example 5(a), 1.69 g of 2-(4-phenylbutyl)phenol (prepared as described in Preparation 3), 1.72 g of 1-t-butoxycarbonyl-2-(2-hydroxyethyl)piperidine, 5.9 g of triphenylphosphine and 3.92 g of diethyl azodicarboxylate were reacted in 75 ml of methylene chloride. The crude oily product, extracted as described in Example 5(a), was purified by column chromatography through silica gel, using a 5:1 by volume mixture of hexane and ethyl acetate as the eluent, to give 1.13 g (yield 34%) of the title compound as an oil.
