Participants

Reaction Steps

To a mixture of 2β-isopropoxy-3α-hydroxy-5α-androstan-17-one (700 mg, 2.0 mmol) and p-toluenesulfonhydrazide (450 mg, 2.4 mmol) was added ethanol (2 mL) and the mixture obtained was heated to reflux for 12 h. Then the reaction mixture was dissolved in CH2Cl2 (150 mL) and washed with water (4×45mL). It was then dried over Na2SO4 and removal of the solvent in vacuo resulted in the crude 2β-isopropoxy-3α-hydroxy-5α-androstan-17-one tosylhydrazone (1.113 g), which was used without further purification for the next step.
