Reaction Steps

In step 1-1, sodium bicarbonate (1.68 g, 20 mmol) was added into a solution of 2,6-dichloro-3-nitropyridine (1.93 g, 10 mmol) and 3-amino benzonitrile (1.18 g, 10 mmol) in acetonitrile and the suspension was heated for 24 hours at 60° C. The mixture was filtered and washed twice with water to give 3-(6-chloro-3-nitropyridin-2-ylamino)benzonitrile (1-1) as a pale yellow solid. 1H NMR DMSO-d6 δ (ppm) 10.24 (s, 1H), 8.57 (d, 1H), 8.09 (m, 1H), 7.93 (m, 1H), 7.62 (m, 2H), 7.08 (d, 1H); m/z 357 M+1.
