Procedure
2-[4-(2-Azepan-1-yl-ethoxy)-benzyl]-2-(4-methoxy-benzenesulfonyl)-pentanoic acid was prepared starting from 2-[4-(2-azepan-1-yl-ethoxy)-benzyl]-2-(4-methoxy-benzenesulfonyl)-pentanoic acid ethyl ester (2 g, 3.76 mmol) dissolved in methanol (300 ml) and 10 N NaOH (15 ml). The resulting mixture was worked up as outlined in example 1. Yield 830 mg (44%); brown solid; mp 55° C.; MS: 504.4 (M+H)+.
