| titleOfInvention | A PROCEDURE FOR THE PRODUCTION OF 21-HYDROXYPREGENES AND PREGNADIENS XANTHTOGENIC ACID AND THEIR SALTS |
| abstract | A process for the production of 21-xanthogenic acids from Δ 4-3,20-diketo-21-hydroxy-pregnenos and Δ 1,4-3,20-diketo-21 hydroxy-pregnadienes or salts of said acids, consisting of in dissolving the 21-hydroxy compound in an organic solvent, at least partially miscible with water, and reacting with an alkali metal hydroxide; the alcoholate thus formed is reacted with carbon disulfide, and the 21-xanthogenic acid thus obtained is released, by adding an acid, after which, if it is desired to obtain a salt of said xanthogenic acid, the xanthogenic acid is neutralized with the base corresponding to the desired salt.
