実験手順

To a solution of 1H-indazole-6-carbonitrile (70 mg, 0.49 mmol) in DMF (5 mL) was added NaH (60% oil dispersion, 39.12 mg, 0.98 mmol) at 0° C. The reaction mixture was stirred at 0° C. for 10 minutes before the addition of 4-chloro-N-(2-methoxypyridin-3-yl)-1,3,5-triazin-2-amine (139.45 mg, 0.59 mmol). Stirring at RT was continued for 2 hr. The reaction mixture was then quenched with water and EtOAc was added. Precipitate formed was collected by suction filtration, then redissolved in DCM and washed with water. Further trituration (9:1 mixture of heptane/Et2O) gave the title compound: 1H (250 MHz, CDCl3, VT @ 323K) δ 4.10 (3H, s), 7.06 (1H, br. s.), 7.60 (1H, dd, J=8.22, 1.37 Hz), 7.91 (1H, dd, J=8.22, 0.76 Hz), 7.97 (2H, d), 8.42 (1H, d, J=0.76 Hz), 8.74 (1H, dd, J=7.84, 1.60 Hz), 8.86 (1H, s), 9.20 (1H, s); m/z=+345.0 (M+H)+.
