| titleOfInvention | Process for preparing 16ª‡-methyl-3ª‰,17ª‡-dihydroxy-í¸-pregnen-20-one |
| abstract | The invention comprises (a) compounds of formula <FORM:1087899/C2/1> wherein R1 is a hydrogen atom or a methyl or ethyl group; and (b) a process for preparing 16a - methyl - 3b ,17a dihydroxy - pregn - 5 en - 20 - one or its 3 - acetate by reaction of a 6b -hydroxy, methoxy or ethoxy-3,5-cyclo-pregn-16 - en - 20 - one with a methyl magnesium halide to give a 16a - methyl - 20 - Grignard adduct, reacting this with excess of an acetylating agent to give a D 17(20) enol acetate, oxidizing this to a 17,20 epoxide, hydrolysing this under alkaline conditions to obtain a compound of the invention, and subjecting this to acidic rearrangement. |
