Description

Изобретение относитс  к способу получени  повых адамантановых производных, в частности к способу получени  1,3,5,7-тетрабромадамантандиола-2 ,6, которые могут найти применение в фармацевтической промышленности , а также в промышленности тонкого органического синтеза.This invention relates to a process for the preparation of new adamantane derivatives, in particular, to a process for the preparation of 1,3,5,7-tetrabromoadmantane-2, 6, which can be used in the pharmaceutical industry, as well as in the fine organic synthesis industry.

Известно восстановление кетогруппы различных углеводородов, замещенных бромом, боргидридом натри  в среде различных органических растворителей.It is known to reduce the keto group of various hydrocarbons substituted by bromine, sodium borohydride in the environment of various organic solvents.

По предлагаемому способу получают 1,3,5,7тетрабромадамантандиол-2 ,6. Процесс восстановлени  боргидритом натри  ведут в водно-спиртовой среде При О-50°С в течение 0,5-2 час.According to the proposed method receive 1,3,5,7 tetrabromaine dandiol-2, 6. The process of sodium borohydrite reduction is carried out in an aqueous-alcoholic medium. At O-50 ° C for 0.5-2 hours.

Пример. В стекл нном реакторе смешивают 1 г 1,3,5,7-тетрабромадамантаидиола-2,6 (0,002 моль) в 12 мл метанола с раствором 0,4 г (0,01 моль) боргидрида натри  тз 13 мл воды. Температуру реакции 20-25°С поддерживают с помошью холодной бани и выдерживают 1 час. Осадок отфильтровывают, промывают водой и подсушивают.Example. In a glass reactor, 1 g of 1,3,5,7-tetrabromadamantaidiol-2,6 (0.002 mol) is mixed in 12 ml of methanol with a solution of 0.4 g (0.01 mol) of sodium borohydride TK 13 ml of water. The reaction temperature of 20-25 ° C is maintained with the aid of a cold bath and kept for 1 hour. The precipitate is filtered off, washed with water and dried.

Продукт очищают перекристаллизацией из гептана Тпл. 205-207°С. Выход 50%.The product is purified by recrystallization from heptane Tpl. 205-207 ° C. Yield 50%.

ИК-спектр не содержит полосы в области 1730-1740 ел;-. Иптенсивные полосы по вл ютс  в област х 1100 и 3500 см, характерные дл  гидроксильной группы.The IR spectrum does not contain bands in the 1730-1740 area; -. Intensive bands appear in the 1100 and 3500 cm regions characteristic of the hydroxyl group.
