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 26.3 g of ethylβ-benzoylamino-β-ethoxyacrylate was then added. The resulting solution was allowed to stand at room temperature for one week. The crystals which precipitated were collected and recrystallized from methanol; thus, 32 g of pale yellow crystals of the objective compound of a melting point of 275° to 278° C. was obtained.
