Participants

Reaction Steps

3,4-Dinitro-benzoyl chloride (0.69 g, 3.0 mmol) in 2 mL toluene was added to a stirred mixture of 2-amino-5-cyanopyridine (0.357 g, 3.0 mmol) and 5 mL pyridine. After stirring overnight at ambient temperature the mixture was concentrated i.vac. The residue was taken up in ethyl acetate and 5% NaHCO3 (aq). The organic layer was washed with water and brine, separated, dried and concentrated i.vac. The residue was purified by chromatography on silica gel (eluent gradient: dichloromethane/ethanol=100:0->100:2).
