Соединени про вл ют высокую физиологическую активность и могут найти применение в фармацевтической промышленности.The compounds exhibit high physiological activity and can be used in the pharmaceutical industry.
Согласно изобретению способ получени ироизводных пиперазина состоит во взаимодействии N-фенацилпиперазина с хлорангидридом кислоты в водной или водноорганическбй среде и полученный при этом в виде хлоргидрата целевой продукт перевод т в основание обычным способом.According to the invention, the process for the preparation of piperazine derivatives is the interaction of N-phenacylpiperazine with an acid chloride in an aqueous or organic-aqueous medium, and the product obtained as a hydrochloride is converted into the base in the usual way.
Пример 1. К раствору 5,5 г (0,02 моль) хлоргидрата М-( -хлорфенацил)-пиперазина в минимальном объеме теплой воды добавл ют 10 мл 20%-ного раствора едкого натра и 30 мл бензола. Тщательно взбалтывают дл перехода всего К-(«-хлорфенацил)-пиперазина в бензол.Example 1. To a solution of 5.5 g (0.02 mol) of M- (-chlorophenacyl) -piperazine hydrochloride in a minimum volume of warm water was added 10 ml of a 20% sodium hydroxide solution and 30 ml of benzene. Thoroughly shake to transfer the entire K - ("- chlorfenacil) piperazine to benzene.
Добавл ют раствор 3,32 г (0,021 моль) л-фторбензоилхлорида и 20 мл бензола и взбалтывают 10 мии. Дают отсто тьс , отдел ют бензольный слой, насыщают его сухим хлористым водородом. Продукт отдел ют и кристаллизуют из метанола, осажда эфиром. Получают 3,45 г (87%) бесцветных кристаллов хлоргидрата Ы-(л-хлорфеиацил)-Ы-(/гфторбензоил )-пиперазина, т. пл. 210°С. Найдено, %: С 58,40; Н 4,96; N 7,12.A solution of 3.32 g (0.021 mol) of l-fluorobenzoyl chloride and 20 ml of benzene is added and shaken for 10 minutes. Allow to stand, separate the benzene layer, saturate it with dry hydrogen chloride. The product is separated and crystallized from methanol, precipitated with ether. Obtain 3.45 g (87%) of colorless crystals of hydrochloride N- (l-chlorfeiacyl) -Y - (/ gfluorobenzoyl) piperazine, so pl. 210 ° C. Found,%: C 58.40; H 4.96; N 7.12.

Пример 2. 2,04 г (0,01 моль) N-фенацилпиперазина раствор ют в 10 мл воды, добавл ют 10 мл 10%-ного раствора едкого натра и 1,55 г (0,011 моль) беизоилхлорида. Взбалтывают 10 мин. Добавл ют 50 мл бензола и экстрагируют в бензол основание продукта. Бензольный слой отдел ют и насыщают сухим хлористым водородом, получа осадок продукта. Осадок кристаллизуют из этанола. Выход 2,62 г (76%), т. пл. 174°С.Example 2. 2.04 g (0.01 mol) of N-phenacylpiperazine is dissolved in 10 ml of water, 10 ml of 10% sodium hydroxide solution and 1.55 g (0.011 mol) of beisoyl chloride are added. Shake 10 min. 50 ml of benzene is added and the product is extracted into the benzene base. The benzene layer is separated and saturated with dry hydrogen chloride to form a product precipitate. The precipitate is crystallized from ethanol. The output of 2.62 g (76%), so pl. 174 ° C.
Отделенное после ацилировани основание можно обработать этаноловым раствором хлористого водорода.The base separated after acylation can be treated with an ethanol solution of hydrogen chloride.
