Abstract

Alkylergolines (I ; R = CH2-CN or CH2CONH2), prolactin inhibitors, were prepd. by two methods. Thus, D-6-methyl-8-substituted ergolin (II) was treated with methylformate and ethanethiol, and the resulting dithioacetal of ergolin converted to I by desulfurization; or D-6-methyl-8-halomethyl ergolin converted to 2-formyl substituted dithioacetal by formylization in the presence of ethanedithiol and 2-methyl substituted dithioacetal by desulfurization, and the resulting compd. reacted with an inorg. cyanide in an inactive solvent followed by hydrolysis to give I.
