Versuchsvorschrift
1-(4-Bromo-benzyl)-4-(4-prop-2-ynyloxy-benzenesulfonyl)-piperdine-4-carboxylic acid was prepared starting from 1-(4-bromo-benzyl)-4-(4-prop-2-ynyloxy-benzene-sulfonyl)-piperdine-4-carboxylic acid ethyl ester (5 g, 9.59 mmol) dissolved in THF:methanol (150:50 ml) and 10 N NaOH (15 ml). The resulting reaction mixture was worked up as outlined in Example 1 (Step 7). Yield 3.4 g (72%); brown low melting solid; MS: 491.9 (M−H)−
