Reaction of 3β-acetoxy-17-chloro-16-formylandrosta-5,16-diene (Compound 3) (0.5 g, 1.329 mmol), pyrazole (136 mg, 1.994 mmol) and K2CO3 (551 mg, 3.99 mmol) as described for Synthesis Example 7 after FCC (silica gel, pet. ether/EtOAc, (4:1)) gave a mixture (341 mg, approx. 3:1) of 3β-acetoxy-17-(1H-pyrazol-1-yl)-16-formylandrosta-5,16-diene and 3β-acetoxy-17-(1H-pyrazol-1-yl)androsta-5-ene. This mixture resisted separation by chromatography.
