実験手順

2-Chloro-6-methyl-nicotinonitrile (25 g, 0.164 mol) and liquid ammonia (250 mL) in 500 mL of ethanol were reacted in a sealed high-pressure vessel at 130° C. for 20 hours. The reaction mixture was concentrated under vacuum and the residue washed with water (2×50 mL) then dried in a vacuum oven for 24 hours to provide the title compound as a light yellow solid (18 g, 82%). 1H NMR (300 MHz, DMSO-d6) δ ppm: 2.30 (s, 3H), 6.52 (d, J=7.7 Hz, 1H), 6.78 (s, 2H), 7.73 (d, J=7.7 Hz, 1H).
