p-Toluenesulfonic acid monohydrate → HCID 86756899, compound

Participants

Reaction Steps

A solution of 0.232 g of (E)-2(R)-[1(S)-(tetrahydro-2(RS)-pyranyloxy)carbamoyl]-4-phenyl-3-butenyl]-2′-isobutyl-4-methyl-2′-(2(RS)-ureidopropionyl)valerohydrazide in 5 ml of methanol was treated with 0.03 g of p-toluenesulphonic acid monohydrate. The mixture was stirred for 2 hours at room temperature and evaporated. The residue was triturated with diethyl ether, filtered off and dried to give 0.168 g of (E)-2(R)-[1(S)-(hydroxycarbamoyl)-4-phenyl-3-butenyl]-2′-isobutyl-4-methyl-2′-(2(RS)-ureidopropionyl)valerohydrazide in the form of a white solid.
