Abstract

Способ получения N-оксоанилов-42-пиразолиндионов-4,5 общей формулыгде R - CH, NH, CHCONH, CHCONH, CHCH(COOH)CHCONH,отличающийся тем, что производное пиразолона-5 общей формулы Iгде R указано выше;X - Cl, Br, CHO,подвергают взаимодействию с 4-нитрозодиэтиланилином в присутствии триэтиламина в среде этанола или диметилформамида с выделением целевого продукта.The method of obtaining N-oxoanilo-42-pyrazolinedione-4,5 of the general formula where R is CH, NH, CHCONH, CHCONH, CHCH (COOH) CHCONH, characterized in that the pyrazolone-5 derivative of the general formula I Br, CHO, is reacted with 4-nitrosodiethylaniline in the presence of triethylamine in ethanol or dimethylformamide to isolate the desired product.
