Halogenation using halo-vilsmeier reagent |
| abstract |
The invention provides an improved process for the preparation of a halogenated steroidal diene. The process involves the simultaneous transformation of the steroidal 3-one to 3-halo and 17-carboxylic acid to 17-carboxamide in a single reaction without the isolation of an intermediate. The process takes place by reacting the steroidal starting material with a halogen-Vilsmeier reagent. |
