Procedure
To a solution of 650 mg (S)-4-[6-Benzyloxy-2-(9H-fluoren-9-ylmethoxycarbonylamino)-hexanoyl]-piperazine-1-carboxylic acid butyl ester in 3.6 ml DMF were added at room temperature 0.91 ml morpholine. After stirring for 2 h the reaction mixture was evaporated and the crude product thus obtained used in the next step without further purification.
