Reaction Steps
A suspension of 5.68 g (20 mmol) of 3-methoxy-8α-estra-1,3,5(10)-trien-17-one and 4.30 g (25 mmol) of benzenesulfonic acid hydrazide in 70 ml of ethanol is mixed with 3 drops of concentrated hydrochloric acid and then allowed to react at a bath temperature of 80–90° C. for three hours while being stirred vigorously. After the reaction solution is cooled, the precipitated product is suctioned off, rewashed with a little cold ethanol, and the hydrazone is dried in a vacuum. 8.10 g (92%) of product, which melts at 183–185° C., is obtained.
