Versuchsvorschrift
1-Benzyl-4-[4-(4-chloro-phenoxy)-benzenesulfonyl]-piperidine-4-carboxylic acid was prepared starting from 1-benzyl-4-[4-(4-chloro-phenoxy)-benzenesulfonyl]-piperidine-4-carboxylic acid ethyl ester (2.11 g, 4.1 mmol) dissolved in TB:methanol (3:1 150 ml) and 10 N NaOH (20 mL). The resulting reaction mixture was worked up as outlined in example 83. Yield 1.11 g (56%); white solid; mp 201° C.; MS: 485.9 (M+H)+
