Versuchsvorschrift

A solution of 0.69 g of (E)-2′-[(1-(9-fluorenylmethyloxycarbonylamino)-1-cyclopentyl)carbonyl]-2(R)-[1(S)-[(tetrahydro-2(RS)-pyranyloxy)carbamoyl]-4-phenyl-3-butenyl]-2′-isobutyl-4-methylvalerohydrazide in a mixture of 6.4 ml of dichloromethane and 1.6 ml of piperidine was stirred at room temperature for 1 hour. The solution was evaporated and the residue was treated with diethyl ether. The ethereal solution was filtered and evaporated. Chromatography on silica gel using methanol/dichloromethane (1:33) for the elution followed by evaporation gave 0.36 g of (E)-2′-[(1-amino-1-cyclopentyl)carbonyl]-2(R)-[1(S)-[(tetrahydro-2(RS)-pyranyloxy)carbamoyl]-4-phenyl-3-butenyl]-2′-isobutyl-4-methylvalerohydrazide in the form of a white foam.
