| titleOfInvention | Production of 6beta-fluoro-delta1,4-pregnadiene derivative |
| abstract | PURPOSE: To produce the titled fluorine-containing steroid compound useful as an anti-inflammatory agent, in high yield, by reacting an alkali metal salt of an organic acid with fluorine gas, reacting the product with Δ 3.5 -pregnadiene derivative, and separating the objective product from the reaction product. n CONSTITUTION: An organic acid alkali metal salt (e.g. CH 3 COONa) is made to react with fluorine gas (usually diluted to ≤20mol% with an inert gas such as N 2 ) preferably in a chlorofluorocarbon solvent at about -75°C. The obtained reaction mixture is made to react with a Δ 3.5 -pregnadiene derivative, and the objective compound is separated from the product by column chromatography, high-performance liquid chromatography, etc. n COPYRIGHT: (C)1985,JPO&Japio |
