Abstract Instead of the usual indolization, when acetaldehyde (2,6-dichloro-4-pyridyl)hydrazone is heated with zinc chloride under the conditions of the Fischer reaction one observes the formation of acetone (2,6-dichloro-4-pyridyl)hydrazone, 1-(2,6-dichloro-4-pyridyl)-5-methylpyrazoline, and 2,6-dichloro-4-aminopyridine, the ratio between which depends on the temperature and duration of the reaction.
