Изобретение относитс  к способу получение новых амидов, которые могут примен тьс  как анксиолитические средства, противосудорожные средства, средства против одьппки и дл  лечени  состо ни  иммунодепрессии.
Цель изобретени  - синтез новых амидов, которые по своей активности превосход т структурные аналоги, обладающие тем же видом активности.
Ц р и М е р. К 25 см сухого тет- рагидрофурана в атмосфере азота добавл ют 1,84 см диизопропиламина. Раствор перемешивают, охлаждают до и ввод т в него, в течение 10 мин 7 см раствора 1,6-мол рного бутйллити  в гексане.
После стабилизации температуры при -70°С ввод т раствор 2,4 г N,N-диэтйл-2-фeшm-4-xинoлин-aцeтaми- да в 10 см тетрагидрофурана. Оставл ют на 30 мин при перемешивании при -70 С, затем медленно добавл ют раствор 0,58 см йодистого металла в 10 см тетрагидрофурана и 0,52 см гексаметилфосфорамида. Перемешивают 3 ч при -70°С, затем 30 мин при -50°С. Потом добавл ют по капл м 3 см абсолютного этанола, затем 2 см лед ной уксусной кислоты. Довод т температуру до О С, затем добавл ют 50 см воды и зкстрагируют 3 раза 50 см этилового эфира. Органкчес - кую фазу промывак)т водой, сушат на
сульфате магни  и вьтаривают при пониженном давлении.
После перекристаллизации остатка из иэопропилового эфира получают 1,65 г Н,К-диэтил-о(,-метил-2-фенил- -4-хинолин-ацетамида с т.пл. .
N,N-Диэтил-2-фeнил-4-xинoлин-aцeт амид может быть получен следующим образом .
Смесь 3 г 2-фенил-4--хинолиН этил- ацетата и 60 см диэтиламина нагревают до 250 с в течение 40 ч. После |охлаждени  избыток диэтиламина выпа- 1ривают,
Остаток хроматографируют на сили- |кагеле со смесью циклогексана - этил |ацетата (50:50 по объему) в качестве растворител . После перекристаллиза- |ции из этилацетата выдел ют 2,05 г И,Ы-диэтил-2-фенил-4-хинолин-ацет- ;амида с т.пл. 86°С. .
2-Фенил-4-хинолин этилацетат получают следующим способом.. : К 40 см сухого тетрагидрофурана в атмосфере азота добавл ют 12,9 см циизопропиламина. Раствор перемешивают , затем охлаждают до --70°С. Пото ввод т за 15 мин 46 см 1., 6-мол рно- ро раствора бутиллити  н гексане, |затем после стабилизатдаи температуры |цо -60 С ввод т за 15 мин 8,1 г 2-фе Ииллепидина в 20 см тетрагидрофура- а, потом довод т до комнатной тем- Ьературы (приблизительно 20°С). Этот t acTBop добавл ют по капл м в атмосфере азота к раствору 9 см диэтил- Карбоната в 50 см тетрагидрофурана, Предварительно охлажденного до -20 С. После окончани  ввещени  оставл ют при перемешивании при комнат йой температуре (приблизительно 20 с) В течение 1 ч.
Затем добавл ют по капл м 25 см абсолютного этанола, потом 10 см Лед ной уксусной кислоты и, наконец, 100 см воды. Тетрагидрофуран выпаривают при пониженном давлении и :Водную фазу поглощают в 200 см эти- Лового эфира. Эфирную фазу промывают Водой, сушат на сульфате магни  и Эьшарив ают при понгокенном давлении. Остаток поглощают 100 ск толуола, :Который снова выпаривают, чтобы удалить уксусную кислоту.
Остаток хроматографируют на сили- жагеле со смесью циклогексана - этил - ацетата (80:10 по объемзО в качестве Э ствог)ител . Получают 7 г 2-фенил-4-хинолин-этилацетата в форме желтого масла. Этот продукт ввод т в ацетон и после присоединени  раствора сол ной кислоты в этиловом эфире выдел ют 5,13 г хлоргидрата-;2-фенил- -4-хинолин-этилацетата с т.пл. 180°С. Предлагаемые соединени  и их соли имеют интересные фармакологические IQ свойства. Эти соединени  св зываютс  с рецепторами бензодиазепинов периферического типа, следовательно, примен ютс  как анксиолитические средства, противосудорожные средства, средства J5 против одьппки и дл  лечени  состо ни  иммунодепрессии.
