Reaction Steps

1200 mg of 4-methyl-2-(2-phenylethyl)phenol were dissolved in 10 ml of N,N-dimethylacetamide, allowed to react with 700 mg of potassium t-butoxide and 1600 mg of (2S,4R)-4-benzyloxy-2-(2-chloroethyl)-1-ethoxycarbonylpyrrolidine and extracted in the same manner as described in step (a) of Example 2. The resulting oily substance was purified by silica gel column chromatography, using a 3:1 by volume mixture of hexane and ethyl acetate as the eluent, to give 1820 mg (yield 73%) of the title compound as an oily substance.
