Procedure

A solution of 2-(1-(2-(4-fluorophenylamino)ethyl)-5-oxo-1H-1,2,4-triazol-4(5H)-yl)-4-methyl-N-(pyridin-3-ylmethyl)thiazole-5-carboxamide (0.10 g, 0.40 mmol) in anhydrous tetrahydrofuran (10 mL) was treated with sodium hydride (60% suspension in mineral oil, 0.02 g, 0.47 mmol) at ambient temperature for 30 minutes, followed by the addition of iodomethane (0.015 mL, 0.24 mmol). The reaction mixture was stirred at ambient temperature for 1 hour, quenched with water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulphate, filtered and concentrated in vacuo. The residue was purified by column chromatography eluted with ethyl acetate to afford the title compound as a white solid in 25% yield (0.03 g): 1H NMR (300 MHz, CDCl3) δ 8.60-8.49 (m, 2H), 8.24 (s, 1H), 7.69-7.59 (m, 1H), 7.35-7.27 (m, 1H), 6.91-6.77 (m, 2H), 6.59-6.49 (m, 2H), 4.69 (s, 2H), 4.15-4.04 (m, 2H), 3.99-3.87 (m, 1H), 3.54-3.44 (m, 2H), 2.98 (s, 3H), 2.39 (s, 3H); MS (ES+) m/z 468.18 (M+1).
