Abstract

The reaction of 3-aminopyridine 1-oxide (1) and 1-methanesulfonylpyrrole (2) with amyl nitrite in acetic acid gave 1-methanesulfonyl-2-(1-oxido-3-pyridyl)pyrrole (3), which was converted into nornicotyrine (4) by successive treatment with phosphorous tribromide and sodium hydroxide solution.
