163 g. of 1-(2-furyl)methyl-5-aminopyrazole (1 mol.) and 248 g. of ethoxymethylene benzoyl acetic acid ethyl ester (1 mol.) are heated at 130° until no more alcohol distils off (approximately 1 hour). The oily residue crystallizes and yields on cooling and recrystallization from hexane 310 g. of [[[1-(2-furyl)methyl-5-pyrazolyl]-amino]methylene]benzoyl acetic acid ethyl ester (85%), m.p. 75°-77°.
