실험 절차

A solution of 4-chloro-2,6-dimethylpyridine (849 mg, 6 mmol), (J. Het. Chem. 1990, 1841), in 2-(methylamino)ethanol (1.35 g, 18 mmol) and 3M ethereal hydrogen chloride (3 drops) was heated at 140° C. for 1 hour. The reaction mixture was allowed to cool and was diluted with water. The insolubles were removed by filtration and the aqueous filtrate was poured onto a suspension of magnesium sulphate (50 g) in ethyl acetate (100 ml). The insolubles were removed by filtration and the filtrate dried (MgSO4) and the solvent removed by evaporation. The solid residue was triturated with ether, collected by filtration and dried under vacuum at 50° C. to give 2-(N-(2,6-dimethyl-4-pyridyl)-N-methylamino)ethanol (960 mg, 90%).
