Abstract

1,133,154. Preparation of 19-nor-androst- 5(10)-ene-3,17 dione. RICHTER GEDEON VEGYESZTI GYAR RT. 18 May, 1966 [22 May, 1965], No. 22050/66. Heading C2U. The invention comprises a process for preparing 19-nor-androst-5(10)-ene-3,17 dione by hydrolysis of a compound of formula wherein R 1 is an alkoxy group and R 2 is a ketal or thioketal group in a water-miscible organic solvent with an organic acid having a dissociation constant in the range 10<SP>-2</SP> to 10<SP>-5</SP> at ambient or elevated temperature.
