実験手順

A mixture of 2-chloro-3-iodo-4-methylpyridine (preparation 28a, 2.0 g, 7.9 mmol) and hydrazine hydrate (1.2 mL, 24.2 mmol) in pyridine (12 mL) under an argon atmosphere was stirred and heated to reflux. After 24 hours, the mixture was cooled and evaporated to dryness. The crude mixture was triturated with water and the solid was filtered and washed with water to give the title compound (1.71 g, 87%) which was used without further purification in the next reaction.
