  Process for the preparation of 3-oxo-17-acetylamino-Ïtiocholan
The subject of the main patent is a process for the production of 3-oxo-17-aeetyl- @mino-androstane, which is characterized in that the 3-oxy-17-acetyl (mino-androstane is treated with oxidizing agents .



   The subject of the present patent is in a process for the preparation of 3-oxo-17-icetylamino-ätiocholan, which is @ennzoichnet, dā 3¯-Oxy-17-acetylamino- itioeholan with an oxidizing agent, before cilliaft with a solution of chromic acid mhydride in glacial acetic acid.



   The compound obtained by the process according to the invention crystallizes in the form of prisms which have a melting point of on 260¯. It is insoluble in water, difficult to get rid of in ether, but soluble in glacial acetic acid and methanol.



     Ma's product is intended to be used as a therapeutic agent or as an intermediate product for the manufacture of valuable drugs.



   example
140 mg 3¯-oxy-17-acetylamino-Ïtiocholan are dissolved in 2.8 cm3 glacial acetic acid. Then 45 mg of chromic anhydride, dissolved in 1.7 cubic meters of glacial acetic acid, are added and the mixture is allowed to stand at room temperature overnight. It is poured into, filtered, and the flocculated reaction product is filtered off and washed with water.



  105 mg of 3-oxo-17-acetylamino-etio-eholane with a melting point of 260, which crystallizes in prisms with a melting point of 260 from aqueous methanol, are obtained.



   The 3¯-Oxy17-acetylamino-ä, tiocholan used as starting material was obtained in the following way:
175 mg of 3-acetoxy-17-acetylamino-ätiocholan are heated to boiling under reflux for 15 minutes with a solution of 0.25 g of sodium hydroxide in 1 cm3 of water and 4 em) of alcohol. The solution is poured into water and the precipitated product is filtered off and washed with water. The 3¯-oxy-17-acetylamino-Ïtiocholane is obtained as a crude product with a melting point of 262¯. Yield 1. 40 mg. After recrystallizing from alcohol, it melts at 264.
