17p-hydroxyandrost-4-en-3-one

A mixture of approximately 11 parts of 17a-(2-carboxyethyl)-17p-hydroxyandrosta-4,6-dien-3-one lactone and 10 parts of thioacetic acid is heated at 85° to 95°C for Vi hour. Excess thioacetic acid is removed by vacuum distillation at this point, and the residue is twice recrystallized from methanol, affording 7a-acetylthio-17a-(2-carboxyethyl)-17p-hydroxyandrost-4-en-3-one lactone, melting at approximately 134° to 135°C. Heated above this melting point, the product solidifies and melts again at approximately 201° to 202°C (with decomposition). [Pg.3063]
