Reaction Steps

A solution of 0.050 g of (E)-2(R)-[1(S)-[(tetrahydro-2(RS)-pyranyloxy)carbamoyl]-4-phenyl-3-butenyl]-2′-isobutyl-4-methyl-2′-(3-phthalimidopropionyl)valerohydrazide in 5 ml of methanol was treated with 0.005 g of p-toluenesulphonic acid monohydrate. The mixture was stirred for 1 hr at room temperature and evaporated. The residue was triturated with diethyl ether, filtered off and dried to give 0.009 g of (E)-2(R)-[1(S)-(hydroxycarbamoyl)-4-phenyl-3-butenyl]-2′-isobutyl-4-methyl-2′-(3-phthalimidopropionyl)valerohydrazide in the form of an off-white solid.
