Procedure

4-(4-methoxy-benzenesulfonyl)-1-(2-phenoxy-ethyl)-piperidine-4-carboxylic acid was prepared starting from 4-(4-methoxy-benzenesulfonyl)-1-(2-phenoxy-ethyl)-piperidine-4-carboxylic acid ethyl ester (5.0 g, 11.1 mmol) dissolved in THF:methanol 3:1 and 10 N NaOH (40 ml). The resulting reaction mixture was worked up as outlined in example 83. Yield 3.0 g (63%); off white powder, mp 235° C.; MS: 420.5 (M+H)+.
