Reaktionsschritte

4-Methylbenzenesulphonic acid hydrazide (525 g) and 4-methylbenzenesulphonic acid (5.25 g) were added to a hot, stirred solution of (5α)-androst-2-en-17-one (700 g) in ethanol (5.6 l) and the solution was heated under reflux for 8 h. The stirred mixture was cooled and further ethanol (1 l) was added to give 4-methylbenzenesulphonic acid [(5α)-androst-2-en-17-ylidene]hydrazide as a crystalline solid.
