In the title compound, C 15 H 13 N 3 OS, the amide H atom interacts with the amide O atom of an adjacent molecule [NÁ Á ÁO = 3.027 (4) A ˚] to form a zigzag chain that runs along the c axis of the monoclinic unit cell.
## Abstract Preparation of 2‐formylindoles was carried out from the appropriate methylindole by oxidation with selenium dioxide and by Vilsmeier formylation. The 2‐(2′‐nitrovinyl)indoles have been obtained by condensa tion of 2‐formylindoles with nitroalkanes in the presence of ammonium chloride in
