反応手順
To a solution of 5-amino-2-trifluoromethylpyridine (0.81 g) in 3 Ml toluene was added chloropyrazine (0.45 Ml, 1.0 equiv) via syringe. The homogeneous solution was heated to 95° C., then cooled to room temperature and concentrated in vacuo. Purification by silica gel chromatography (40% EtOAc in hexanes) afforded the title compound: 1H NMR (400 MHz, CHLOROFORM-D) δ ppm 7.5 (s, 1H) 7.6 (s, 1H) 8.0 (s, 1H) 8.2 (s, 1H) 8.4 (s, 2H) 8.8 (s, 1H); (M+H)+241.1.
