p-Toluenesulfonic acid monohydrate → HCID 86756901, compound

Participants

Reaction Steps

A solution of 0.590 g of (E)-2(R)-[1(S)-(tetrahydro-2(RS)-pyranyloxy)carbamoyl]-4-phenyl-3-butenyl]-2′-isobutyl-4-methyl-2′-[2-(dimethylamino)acetyl]valerohydrazide in 10 ml of methanol was treated with 0.210 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 0.478 g of (E)-2(R)-[1(S)-(hydroxy-carbamoyl)-4-phenyl-3-butenyl]-2′-isobutyl-4-methyl-2′-[2-(dimethylamino)acetyl]valerohydrazide p-toluenesulphonate in the form of a white solid.
