Reaction Steps

A solution of 0.150 g of (E)-2(R)-[1(S)-[(tetrahydro-2(RS)-pyranyloxy)carbamoyl]-4-phenyl-3-butenyl]-2′-(4(RS)-hydroxyvaleryl)-2′-isobutyl-4-methylvalerohydrazide in 5 ml of methanol was treated with 0.015 g of p-toluenesulphonic acid monohydrate. The mixture was stirred at room temperature for 2 hours and evaporated. The residue was triturated with diethyl ether, filtered off and dried to give 0.027 g of (E)-2(R)-[1(S)-(hydroxycarbamoyl)-4-phenyl-3-butenyl]-2′-(4(RS)-hydroxyvaleryl)-2′-isobutyl-4-methylvalerohydrazide in the form of a white solid.
