A procedure similar to that described in Example 3(b) was repeated, except that S-2-pyridyl 3-cyanoandrosta-3,5-diene-17β-thiocarboxylate [prepared as described in Example 3(a)] and 1,2-diphenylethylamine were employed as starting materials, in relative proportions similar to those used in that Example, to give the title compound in a quantitative yield.
