Reaction Steps

A mixture of 16α-methylprogesterone (792 mg) , DDQ (575 mg) and benzene are heated at reflux for 28 hr, after 20 hr additional DDQ (70 mg) is added. After refluxing, the mixture is cooled to 20°-25°, filtered followed by basic workup (ether - potassium carbonate - magnesium sulfate) to give 16α-methylpregna-1,4-diene-3,20-dione.
