HCID 8076Glycol monoethyl ether溶媒

実験手順

1.0 g (7.8 mmol) 2-chloro-5-methylpyridine are stirred under reflux in 5.7 ml (5.9 g, 117.6 mmol) hydrazine hydrate for 12 h. 10 ml ethylene glycol monoethyl ether are added to the cooled reaction mixture and the solvent is then removed completely on a rotary evaporator. This working step is repeated twice, methylene chloride is then added to the residue, the precipitate is filtered off, the filtrate is concentrated in vacuo and the residue is dried in vacuo.
