To a mixture of 2-fluoro-3-methylbenzonitrile (4.0 g, 29.6 mmol) and 2H-1,2,3-triazole (2.04 g, 29.6 mmol) in DMF (80 mL) was added potassium carbonate (8.26 g, 59.2 mmol). The resulting mixture was heated to 120° C. for 2 h. The mixture was cooled, diluted with water and extracted with EtOAc. The organic layers were combined, dried over Na2SO4, filtered and concentrated. The residue was purified by FCC (SiO2, ethyl acetate/hexanes, gradient 0-50%) to yield the title compound (1.5 g, 26%). MS (ESI) mass calcd. for C10H8N4, 184.2; m/z found, 185.1 [M+H]-F. 1H NMR (500 MHz, CDCl3): 7.95 (s, 2H), 7.66 (d, J=7.7, 0.7 Hz, 1H), 7.59 (d, J=7.8, 0.6 Hz, 1H), 7.50 (dd, J=9.8, 5.7 Hz, 1H), 2.20 (s, 3H).
