Reaction Conditions

Reaction Steps

To a slurry of N-(2-chloro-6-methyl-3-nitropyridin-4-yl)-5-fluoropyrimidin-2-amine (13 g, 45.8 mmol) in ethanol (300 mL) was added 10% Pd/C (100 mg). The reaction was stirred for 10 h under a hydrogen atmosphere after which time the reaction was filtered and the filtrate was concentrated. The residue was diluted with ethanol (200 mL) and cooled to 0° C. Isoamyl nitrite (4.0 g, 34.0 mmol) and HBF4 (5.5 g, 34.0 mmol) were added and the reaction was stirred for 30 min at 0° C. followed by rt for 10 h. Evaporation of the solvents followed by recrystallization afforded the product as a white solid (3.2 g, 48%). MS (ESI) mass calcd. C10H7FN6, 230.07. m/z found, 231.2 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ 9.44 (s, 1H), 9.17 (s, 2H), 8.14 (s, 1H), 2.70 (s, 3H).
