Reaction Steps

A mixture of K2CO3 (2.63 g, 19.0 mmol), 5-(5-methyl-1H-1,2,4-triazol-3-yl)-3-(4-(trifluoromethoxy)phenyl)-1,2,4-oxadiazole (Intermediate B, 3.70 g, 11.9 mmol) and 3-(bromomethyl)phenol (1.78 g, 9.52 mmol) was dissolved in THF (48 mL) and stirred at 50° C. for 16 h. The reaction mixture was filtered, the solvent was removed under reduced pressure, and the residue was purified by silica gel chromatography (0% to 80% EtOAc in Hexanes) to afford the title compound. MS (ES+) C19H14F3N5O3 requires: 417. found 418 [M+H]+; 1H-NMR (600 MHz, CD3OD) δ ppm 8.22 (d, J=8.8 Hz, 2H), 7.61 (d, J=8.0 Hz, 2H), 7.19 (d, J=7.8 Hz 1H), 6.72 (m, 2H), 6.67 (s, 1H), 5.49 (s, 2H), 2.56 (s, 3H).
