A mixture of 3-fluoro-1-[(4-methyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)methyl]-4-(trifluoromethyl)pyridin-2(1 H)-one (8-8; 30 mg; 0.103 mmol), 3-(difluoromethyl)-5-hydroxybenzonitrile (8-7; 34.7 mg; 0.205 mmol) and K2CO3 (28.4 mg; 0.205 mmol) was heated to 75° C., and stirred overnight. After cooling to room temperature, the mixture was diluted with water and extracted with CH2Cl2. The combined organic extracts were dried (MgSO4) and concentrated in vacuo. Purification by mass-directed HPLC provided 2.1 mg (0.0048 mmol; 4.6%) of the title compound as a white solid. 1H NMR (400 MHz, DMSO): δ 11.70 (s, 1 H); 7.90 (d, J=7.3 Hz, 1 H); 7.80 (d, J=8.5 Hz, 2 H); 7.57 (s, 1 H); 7.05 (t, J=55.2 Hz, 1 H); 6.69 (d, J=7.3 Hz, 1 H); 5.17 (s, 2 H); 3.10 (s, 3 H).
