An efficient method for synthesis of 6-alkynyl-substituted androstane derivatives was developed via the Pd-catalyzed Sonogashira—Hagihara coupling reaction. The use of AgCl as the cocatalyst (instead of traditionally used CuI) was shown to increase the activity of the catalytic system in several cases.
