Abstract

4 ated to give%-methyll-thieno (3, 2-b) indole. Buii-Hoi7 has recently performed the same series of operations with substituted arylhydrazines and obtained yields from thirty to one hundred per cent. The deep halochromic coloration of our 4-thieno-(3, 2-b) indole with sulfuric acid, its fluorescence, and its extremely dark red picrate are characteristic of the other known thienoindoles as well as the carbazoles.
