Изобретение относитс к способу .получени соединений, которые могут найти применение в качестве промежуточных продуктов в синтезе биолопически-активных веществ.The invention relates to a method for the preparation of compounds which can be used as intermediates in the synthesis of biolopic-active substances.
Предлагаемый способ получени производных 2-метил-5-арилтиено-(3,2-&) пиррола общей формулыThe proposed method for the preparation of 2-methyl-5-arylthieno- (3,2-&) pyrrole derivatives of the general formula
где R-Я-алкил; R-а|рил, заключаетс в том, что анилинокетоны подвергают взаимодействию с хлоргидратом З-амино-4-карбалкокси-б-метилпиофена при нагревании до ,140- 160°С с последующим выделением целевого продукта известным способом.where R is Ya-alkyl; R-aryl, is that aniline ketones are reacted with 3-amino-4-carbalkoxy-b-methylpyophene hydrochloride when heated to 140-160 ° C, followed by isolation of the desired product in a known manner.
Пример 1. Этиловый эфир 2,6-диметил-5фенилтиено- (3,2-6)пиррол-3-карбоновой кислоты .Example 1. 2,6-dimethyl-5-phenyl-thieno- (3,2-6) pyrrole-3-carboxylic acid ethyl ester.
А. Нагревают 1,6 г (0,007 моль хлоргидрата 3-амино-4-карбэтокси-5-метилтнофена с 1,6 г (0,007 моль а-анилинопропиофенона в течение 10 мин при 140-160°С. Затем реакционную смесь охлаждают до комнатной температуры . Образовавшийс в результате реакцииA. Heat 1.6 g (0.007 mol of 3-amino-4-carbethoxy-5-methylthofen hydrochloride with 1.6 g (0.007 mol a-anilinopropiophenone for 10 min at 140-160 ° C.) Then the reaction mixture is cooled to room temperature temperature. The resulting reaction

Б. Нагревают 2,2 г (0,01 моль) хлоргидрата 3-амино-4-карбэтокси-5-метилтиофена и 2,2 г (0,01 люль) а-анилинопропиофенона в течение 1 час при 140-160°С. Выделение вещества провод т в услови х примера 1, А. Выход этилового эфира 2,6-ди.метил-5-фенилтиено (3,2-&)пиррол-3-карбоновой кислоты 1,2 г (41%); т. пл. 81-:82°С (из метанола). Соединение не показывает депрессии с образцом изB. Heat 2.2 g (0.01 mol) of 3-amino-4-carbethoxy-5-methylthiophene hydrochloride and 2.2 g (0.01 lyum) a-anilinopropiophenone for 1 hour at 140-160 ° C. The substance was isolated under conditions of example 1, A. The yield of 2,6-dimethyl-5-phenylthieno ethyl ester (3,2-пир) pyrrole-3-carboxylic acid was 1.2 g (41%); m.p. 81-: 82 ° C (from methanol). The compound shows no depression with the sample from
