Reaction Conditions

Reaction Steps

To a solution of trifluoro-methanesulfonic acid 4,6-dimethyl-pyridin-2-yl ester (0.6 g, 2.35 mmol) in diglyme (2 mL) was added N*1*-(4-nitro-phenyl)-ethane-1,2-diamine (0.51 g, 2.82 mmol). The reaction mixture was heated to 165° C. for 24 h. The resulting reaction mixture was concentrated under reduced pressure and the residue diluted with chloroform. The organic layer was washed with brine and water and dried over sodium sulfate. The solvent was evaporated and the crude residue was purified by column chromatography (60-120 mesh) using 20% ethyl acetate/petroleum ether as eluent to afford N-(4,6-dimethyl-pyridin-2-yl)-N′-(4-nitro-phenyl)-ethane-1,2-diamine (0.38 g, 55%) as a cream solid.
