Abstract
Description
Изобретение относится к способу 1получения новых соединений, которые могут найти применение в медицине.The invention relates to method 1 for the preparation of new compounds that may find application in medicine.
Известен способ получения эфиров азотной кислоты нитрированием спиртов азотной кислотой (Ί ].A known method of producing esters of nitric acid by nitration of alcohols with nitric acid (Ί].
Цель изобретения - разработка способа получения новых производных пиридина, которые.обладают ценными фармакологическими свойствами. 'The purpose of the invention is the development of a method for producing new pyridine derivatives, which possess valuable pharmacological properties. ''

Процесс предпочтительно проводят в среде инертного растворителя, выбранного из хлороформа или дихлорметана при температуре от ~5°С до ком·1 натной в течение 1-3 ч.The process is preferably carried out in an inert solvent selected from chloroform or dichloromethane at a temperature of from ~ 5 ° C to com · 1 natnoye for 1-3 hours
Пример. Ν-(2-0ксиэтил/никотинамид нитрат (1,145 г) постепенно прибавляют к 3 мл дымящейся азотной кислоты, которую охлаждают до температуры от -10 до -5°С при перемешивании. После перемешивания еще в течение одного часа при температуре от 0 до ~5°С к раствору добавляют диэтиловый эфир, чтобы осадить 1,15 г нитрата Ν-(2-оксиэтил/никотинамида азотнокислого сложного эфира в виде бесцветных кристаллов. Кристаллы растворяют в водном растворе карбоната натрия и добавляют этилацетат. Этилацетатный слой отделяют, высушивают над сульфатом натрия и выпаривают под пониженным давлением. Остаток перекристаллизовывают из диэтилового эфира и получают азотнокислый эфир Ν-(2-оксиэтил)никотинамида. Пе-3 942593 рекристаллизацией из диэтилового эфира получают бесцветные кристаллы, имеющие точку плавления 90-92°С.Example. Ν- (2-0xethyl / nicotinamide nitrate (1.145 g) is gradually added to 3 ml of steaming nitric acid, which is cooled to a temperature of from -10 to -5 ° C with stirring. After stirring for another hour at a temperature of from 0 to ~ At 5 ° C, diethyl ether was added to the solution to precipitate 1.15 g of Ν- (2-hydroxyethyl / nicotinamide nitrate ester nitrate as colorless crystals. The crystals were dissolved in an aqueous solution of sodium carbonate and ethyl acetate was added. The ethyl acetate layer was separated, dried over sulfate sodium and evaporated under pon reduced crystallization from diethyl ether to give Ν- (2-hydroxyethyl) nicotinamide nitrate. Pe-3 942593 recrystallized from diethyl ether to give colorless crystals having a melting point of 90-92 ° C.
