3-(4-Acylaminopyrazol-5-yl)-4-methylindoles (13a,b), under Bischler-Napieralski reaction conditions, undergo cyclization at the pyrrolic carbon-2 with ultimate formation of the corresponding pyrazolo[3,4:5′,6′]pyrido[3,4-b]indoles (14a,b) as evidenced by crystal structure analysis of 14a.

Keywords: Bischler-Napieralski Reaction; Directed Cyclization; Pyrazolopyridoindoles
