Pyrolysis of 2‐ethyl‐5‐methylpyrroline ( 1 ) results in formation of 2,5‐dimethylpyrrole, 2‐ethyl‐5‐methylpyrrole, 2‐ethylpyrrole and other minor products. Loss of a hydrogen atom or methyl radicals is suggested as the first step in these reactions. Support for the former comes from hydrogen atom abstraction by photo‐excited benzophenone. The mass spectral reactions of 1 are briefly considered.
