Description

Известны способы получени  ацетата дегидроандростерона из его семикарбазона путем взаимодействи  последнего, например, с пировиноградной кислотой, опиановой кислотой, муравьиным альдегидом и т. д.Methods are known for producing dehydroandrosterone acetate from its semicarbazone by reacting the latter with, for example, pyruvic acid, opioic acid, formic aldehyde, etc.

Особенность предлагаемого способа заключаетс  в том, что ацетат дегидроандростерона получают путем взаимодействи  его семикарбазона с левулиновой кислотой.A feature of the proposed method is that dehydroandrosterone acetate is obtained by reacting its semicarbazone with levulinic acid.

Пример. Раствор 20 г семикарбазоиа ацетата дегидроаидростерона и 50 г левулиновой кислоты в 20 мл 80%-ной уксусной кислоты нагревают при температуре 115° в течение 1 часа. Затем реакционную массу обрабатывают 600 мл воды.Example. A solution of 20 g of semicarbase acetate dehydroaidrosterone and 50 g of levulinic acid in 20 ml of 80% acetic acid is heated at a temperature of 115 ° for 1 hour. Then the reaction mass is treated with 600 ml of water.

Выпадающий остаток отфильтровывают , сушат и экстрагируют эфиром . Остаток после отгонки эфира перекристаллизовывают из метанола .The precipitate is filtered off, dried and extracted with ether. The residue after distillation of the ether is recrystallized from methanol.

Получающийс  ацетат дегидроандростерона имеет темнературу плавлени  168-169°. Выход составл ет 69-70% (по весу).The resulting dehydroandrosterone acetate has a melting point of 168-169 °. The yield is 69-70% (by weight).

Предмет изобретени Subject invention

Способ получени  ацетата дегидроандростероиа из его семикарбазона , отличающийс  тем, что ацетат дегидроандростерона получают взаимодействием его семикарбазона с левулиновой кислотой.A method of producing dehydroandrosterol acetate from its semicarbazone, characterized in that dehydroandrosterone acetate is obtained by reacting its semicarbazone with levulinic acid.
