Temperature: 0 °C

Procedure

500 mg (1.30 mmol) of 1-(4′-aminobiphenyl-4-sulfonyl)octahydrocyclopenta[b]pyrrole-2-carboxylic acid were dissolved in 3 ml of DMF, after which the solution was cooled down to 0° C. in an ice bath and 2.6 mmol of pyridine were added. After the mixture had been stirred at 0° C. for 15 min, 1.40 mmol of methanesulfonyl chloride in 3 ml of DMF were added. The reaction solution was then stirred at room temperature for a further 6 h. The crude product was purified using chromatographic methods.
