Procedure

4-(4-Butoxy-benzenesulfonyl)-1-[4-(2-piperidin-1-yl-ethoxy)-benzyl]-piperidine-4-carboxylic acid was prepared starting from 4-(4-Butoxy-benzenesulfonyl)-1-[4-(2-piperidin-1-yl-ethoxy)-benzyl]-piperidine-4-carboxylic acid ethyl ester (5.8 g, 10 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 4.8 g (86%); Spongy brown solid; mp 98° C.; MS:559.6 (M+H)+
