| titleOfInvention | PROCEDURE FOR THE PREPARATION OF 16-METHYLESTEROIDS. |
| abstract | Procedure for the preparation of 16-nethyl steroids of the general formula I **(See formula)** in which RO means an esterified or etherified hydroxy group and R1 means F, Cl, Br, CH3 or CF3 and where an additional double bond may optionally be present in position 6 (7), characterized in that a 3-hydroxy-l6-methyl-steroid of the general formula II **(See formula)** in which R1 has the indicated significance and where an additional double bond may eventually be present in position 6 (7), or a 3-position esterified derivative suitable for reaction of one of such 3-hydroxy-16-methyl-steroids is treated with an esterifying or etherifying agent of the general formula ROH in which R has the indicated significance, or with a derivative suitable for the reaction of one of such compounds or because in a steroid that otherwise corresponds to formula I, a functionally altered 20-preserve group is solvolitically released.
