Procedure

To a solution of 114 mg (S)-2-Benzyloxycarbonylamino-4,4-difluoro-butyric acid were added 0.11 ml N-ethylmorpholine, 138 mg TOTU and 66 mg 1-ethoxycarbonylpiperazine. After stirring for 12 h the reaction mixture was diluted with ethyl acetate and washed with aqueous LiCl (4%), 0.1 M HCl, saturated aqueous NaHCO3 and brine. The crude product obtained was used without further purification. Yield: 168 mg
