Procedure
3-(4-Hydroxyphenyl)-2-ethoxybutanoic acid ethyl ester was alkylated with 2-(4-methanesulfonyloxyphenyl)ethylmethanesulfonate (described in Example 1a) using the same method as in Example 1(b) to give 2-ethoxy-3-{4-[2-(4-methanesulfonyloxyphenyl)ethoxy]-phenyl}butanoic acid ethyl ester as a diastereomeric mixture.
