A solution of 2-(4-(4-methyl-5-(pyridin-3-ylmethylcarbamoyl)thiazol-2-yl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)ethyl methanesulfonate (0.10 g, 0.23 mmol) and (4-fluorophenyl)methanamine (0.09 g, 0.69 mmol) in anhydrous methanol (5 mL) was heated at reflux for 6 hours. The solvent was removed in vacuo and the residue was purified by column chromatography eluted with ethyl acetate to afford the title compound as a white solid in 66% yield (0.07 g): mp 106-107° C. (ethyl acetate/hexane); 1H NMR (300 MHz, CDCl3) δ 8.59 (br s, 1H), 8.56-8.47 (m, 1H), 8.25 (s, 1H), 7.73-7.65 (m, 1H), 7.32-7.18 (m, 3H), 7.00-6.89 (m, 2H), 6.44 (t, J=5.8 Hz, 1H), 4.59 (d, J=5.8 Hz, 2H), 3.98 (t, J=5.8 Hz, 2H), 3.77 (s, 2H), 3.00 (t, J=5.8 Hz, 2H), 2.64 (s, 3H); MS (ES+) m/z 468.2 (M+1).
