1-(4-Bromo-benzyl)-4-(4-pent-2-ynyloxy-benzenesulfonyl)-piperdine-4-carboxylic acid was prepared starting from 1-(4-bromo-benzyl)-4-(4-pent-2-ynyloxy-benzenesulfonyl)-piperdine-4-carboxylic acid ethyl ester (2.64 g 4.8 mmol) dissolved in THF:methanol (100:50 ml) and 10 N NaOH (10 ml). The resulting reaction mixture was worked up as outlined in Example 1 (Step 7). Yield 1.6 g (65%); off white solid; mp 217° C.; MS: 521.9 (M+H)+
