実験手順

To a suspension of 4-methyl-2-(5-oxo-1H-1,2,4-triazol-4(5H)-yl)-N-(pyridin-3-ylmethyl)thiazole-5-carboxamide (0.15 g, 0.47 mmol) and potassium carbonate (0.10 g, 1.47 mmol) in N,N-dimethylformamide (2 mL) was added (2,2-difluorocyclopropyl)-methyl methanesulfonate (0.13 g, 0.70 mmol). The reaction mixture was kept stirring at ambient temperature for 20 hours, diluted with ethyl acetate (100 mL) and washed with water and brine. The organic solution was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated in vacuo and the residue was purified by column chromatography to afford the title compound in 41% yield (0.08 g): mp 160-161° C.; 1H NMR (300 MHz, CDCl3) δ 8.53-8.41 (m, 2H), 8.24 (s, 1H), 7.69-7.62 (m, 1H), 7.27-7.16 (m, 2H), 4.54 (d, J=5.8 Hz, 2H), 4.00-3.81 (m, 2H), 2.58 (s, 3H), 2.08-1.91 (m, 1H), 1.56-1.41 (m, 1H), 1.40-1.10 (m, 1H); 13C NMR (75 MHz, CDCl3) δ 161.8, 153.3, 150.9, 149.8, 149.1, 148.7, 135.8, 133.9, 131.1, 123.7, 121.8, 112.7, 43.2, 41.5, 20.8, 17.2, 15.4; MS (ES+) m/z 407.1 (M+1).
