The mass spectra of 2′‐OH, 2′‐NH 2 and 2′‐CH 3 ‐dihydro‐2‐stilbazole derivatives show an interesting hydrogen migration. The hydrogen migration is shown to be taking place from the above mentioned substituents to the nitrogen of the pyridine ring followed by a β‐cleavage giving rise to a common ion e at m/e 93, perhaps through an 8‐membered transition state.
