Description
Изобретение может найти применение в качестве фармакологически активного соединели .The invention may find use as a pharmacologically active compound.
Предлагаемый способ получени М,М-малонил-бг с-новокаиндихлоргидрата заключаетс в том, что основание новокаина конденсируют с недОКисью углерода в 1бензоле и затем леревод т полученный продукт в дихлоргидрат обычным способом.The proposed method for the production of M, M-malonyl-BG with novocaine dichlorohydrate consists in the fact that the base of novocaine is condensed with carbon dioxide in 1 benzene and then the resulting product is transferred to the dihydrochloride in the usual way.
Указанное соединение, же ка.к и способ его .получени , в литературе не описаны.The indicated compound, as well as its method of preparation, is not described in the literature.
Способ состоит в следующем. Через раствор 10 г основани новокаина в 220 мл безводного бензола пропускают двукратный избыток газообразной недокиси углерода, полученной ранее описанным методом. Реакцию лровод т при обычной температуре. Постепенно раствор окрашиваетс в красный цвет, что объ сн етс образованием некоторого количества «красного полимера недокиси углерода. После выстаивани смеси в течение суток бензол сливают, а оставшийс смолообразный остаток обрабатывают Зо/о-ным едким натром при нагревании на вод ной бане. Затем делают четыре выт жки диэтиловым эфиром (поThe method consists in the following. Through a solution of 10 g of base of novocaine in 220 ml of anhydrous benzene, a two-fold excess of gaseous carbon dioxide obtained by the previously described method is passed. The reaction is carried out at ordinary temperature. Gradually, the solution turns red, which is due to the formation of a certain amount of red carbon-dioxide polymer. After allowing the mixture to stand for 24 hours, the benzene is poured off, and the remaining gummy residue is treated with 30% sodium hydroxide when heated in a water bath. Then do four stretches with diethyl ether (according to

Полученный50 ml and the solution is evaporated to 1/4 of the original volume. After it is cooled, crystals of N, M-malonyl-byc-novocaine with m. Pl fall out. 108-110 ° C (from benzene). Received by
продукт раствор ют в небольшом количестве спирта и к смеси доливают рассчитанное количество спиртового раствора НС1. После некоторого сто ни выоавшие кристаллы отфильтровывают и сушат под вакуумом.the product is dissolved in a small amount of alcohol and a calculated amount of an alcoholic solution of HCl is added to the mixture. After some standing, the dried crystals are filtered and dried under vacuum.
Выход продукта около 40о/о, т. лл. 197- 198°С. Веш,ество хорошо растворимо в воде, хуже - Б этаноле, плохо - в органических растворител х.The product yield is about 40o / o, so l. 197-198 ° C. It is well soluble in water, worse - ethanol, poorly - in organic solvents.
