Procedure

1 g of octahydrocyclopenta[b]pyrrole-2-carboxylic acid (6.45 mmol) was dissolved in 20 ml of DMF, after which 3 equivalents of a 3N solution of NaOH (6.45 ml) were added at 0° C. After 10 min, a solution of 1.55 g of 4-acetylbenzenesulfonyl chloride (1.1 equivalents, 7.1 mmol) in 8 ml of DMF was slowly added dropwise; after it had reached RT, the mixture was stirred at 40° C. for a further 6 h and, after that, the solvent was removed under reduced pressure. The crude product was purified chromatographically.
