Participants

Reaction Steps

Into a mixed solution of 50 ml of methanol, 50 ml of triethylamine and 50 ml of glacial acetic acid there was dissolved 18.8 g of p-sulfophenyl hydrazine, to which was added 23.5 g of ethylβ-methanesulfonylamino-β-ethoxyacrylate. The resulting solution was allowed to stand at room temperature for one week. The crystals precipitated were collected and recrystallized from methanol; thus 29 g of plate-like crystals of the objective compound of a melting point of 236° to 238° C. was obtained.
