Reaction Steps

Following a procedure similar to that described in Example 2(c), but using 100 mg of N-t-butyl-3-oxo-4-androstene-17β-carboxamide (prepared as described in Preparation 1), 0.2 ml of diethyl cyanophosphate and 200 mg of a boron trifluoride-diethyl ether complex, 86 mg of the title compound were obtained as a crystalline substance, melting at 198° to 200° C.
