Procedure

0.106 ml of benzhydrylamine were added to a solution of 100 mg of 3-cyanoandrosta-3,5-diene-17β-carboxylic acid [prepared as described in Example 1(b)], a catalytic amount of 4-dimethylaminopyridine and 0.131 ml of triethylamine in 4 ml of methylene chloride. 88.0 mg of tosyl chloride were then divided into three portions and added to this reaction mixture at 30 minute intervals at room temperature, whilst stirring. One hour after finishing the addition of the tosyl chloride, the reaction mixture was diluted with methylene chloride, and washed with 1N aqueous hydrochloric acid, with water, with an aqueous solution of sodium hydrogencarbonate, and with a saturated aqueous solution of sodium chloride, in that order. It was then dried over anhydrous magnesium sulfate, and concentrated by evaporation under reduced pressure. The resulting residue was crystallized from acetone, to give 138 mg (yield 92%) of the title compound.
