Procedure
A solution of 626 mg (1.94 mmol) of tert.-butyl (3-chloropropyl)-[2-(4-cyanophenyl)ethyl]carbamate and 5.0 ml of trifluoroacetic acid in 20 ml of dichloromethane was stirred at room temperature for 1.5 hours and then evaporated to dryness. The residue was triturated with diethyl ether. The precipitate formed was then filtered off and dried under reduced pressure over calcium chloride. The product obtained in this manner was reacted further without additional purification.
