Participants

Reaction Steps

A solution of 1.26 g of 2′-(N-benzyloxycarbonyl-D-alanyl)-2(R)-[1(RS)-(tert.-butoxycarbonyl)-4-phenylbutyl]-2′-isobutyl-4-methylvalerohydrazide in 5 ml dichloromethane was treated with 5 ml of trifluoroacetic acid and the mixture was stirred at room temperature for 2 hours. The solvent was evaporated to give 1.30 g of 2′-(N-benzyloxycarbonyl-D-alanyl)-2(R)-[1(RS)-(carboxy)-4-phenylbutyl]-2′-isobutyl-4-methylvalerohydrazide in the form of a pale yellow foam.
