Versuchsvorschrift

2-Chloro-4-cyanopyridine (0.40 g, 2.9 mmol) was dissolved in N-methylpyrrolidone (2.0 ml), and N-methyl-N-benzylamine (1.0 ml, 7.8 mmol) was added thereto. The reaction mixture was stirred at 100° C. for 2.5 hrs, combined with water, extracted with ethyl acetate, washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was subjected to a silica gel (50 g) column chromatography, eluted with hexane-ethyl acetate (3:1, v/v) to give the titled compound (0.47 g, 72%).
