17alpha-Ethynyl-19-nortestosterone 17-heptanoate Usage And Synthesis
OriginatorNorigest,Schering
Manufacturing Process1 g 17-ethinyl-19-nor-testosteron was refluxed with 5 ml of enanthic acid anhydride on an oil bath at temperature 180°C 17 hours. Then the reaction mixture was distilled with water steam to the full disappearence of smell of enantic acid. After that it was washed with 2 N sodium hydroxide and finally with water to neutral, dried over sodium sulfate and evaporated to dryness. The oily residue was rubbed with some drops of methanol and stood at -8°C 24 hours to give the crystals of 3-endol diester; MP: 82°-84°C, 2 g of it was dissolved in 120 ml of methanol and heated with 1.2 ml concentrated hydrochloric acid. The partly saponified product was distilled with water steam to full disappearence of smell of enantic acid. The residue was mixed with ether, washed with 2 N sulfuric acid, 2 N sodium hydroxide, finally with water to neutral dried over sodium sulfate and evaporated to dryness. The residue was stirred with pentane and cooled for crystallization. Pure enanthate was crystallized after repeated solution in pentane. 17-α-Ethinyl-19nortestosterone enanthate had MP: 68°-71°C.

World Health Organization (WHO)Norethisterone enantate was introduced in 1978 for use as a longacting injectable contraceptive. Risk-benefit judgements differ significantly from country to country, having regard to differing national circumstances. Norethisterone enantate is, however, widely available and is included as a complementary drug in the WHO Model List of Essential Drugs. (Reference: (WHODI) WHO Drug Information, 2(1), , 1988)
