Procedure

0.935 g of 1-((1R,5S,6R)-6-(4-amino-phenyl)-3-aza-bicyclo[3.2.0]hept-3-yl)-propan-1-one (3.83 mmol) were dissolved in 30 ml of tetrahydrofuran and 0.795 g of 4-isopropylbenzenesulfonyl chloride (3.64 mmol) and 1.6 ml of triethylamine (11.48 mmol) were added. After stirring for 18 h at room temperature, the solvent was evaporated under reduced pressure, the remaining material was partitioned between diethyl ether and water that was adjusted to alkaline pH with 1 N aqueous sodium hydroxide. The aqueous layer was reextracted three times with diethyl ether, and the combined organic layers were dried over magnesium sulfate, filtered, and the solvent was evaporated to yield 1.76 g of crude product that was used in the subsequent reaction step without further purification.
