Procedure
To a stirred solution of 6-chloro-4-(isopropylamino)nicotinamide (17) (2.5 g, 11.7 mmol) in DMF (10 mL), cyanuric chloride (11.7 mmol, 1 equiv.) was added at 0° C. and stirred for 2 h. The reaction mixture was quenched with ice-cool water and extracted twice using EtOAc. The organic layer was collected, dried over Na2SO4, filtered and concentrated. The crude material was purified by column chromatography, silica gel (60-120 mesh) and EtOAc: pet Ether as eluent to furnish 6-chloro-4-(isopropylamino)nicotinonitrile. 1H NMR: 400 MHz, CDCl3: δ 1.32 (d, J=6.40 Hz, 6H), 3.69-3.79 (m, 1H), 4.91 (bs, 1H), 6.57 (s, 1H), 8.23 (s, 1H).
