실험 절차

To a mixture of 4-(5-(1-ethoxyvinyl)-2-fluoropyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (100 mg, 0.363 mmol) and 6-chloro-5-methoxypyridin-3-amine (Small Molecules, Inc) (86 mg, 0.545 mmol) in 1 mL of THF and 0.3 mL of DMF at 0° C. was added sodium bis(trimethylsilyl)amide (1.09 mL of 1.0 M solution in THF, 1.09 mmol) dropwise and the dark red solution was stirred at this temperature for 30 min. It was quenched with 4 mL of 0.5N HCl and stirred at RT for 10 min. The mixture was treated with 1 N NaOH to pH of about 8. It was extracted twice with EtOAc (30 mL). The combined organic phases were washed with brine and dried over Na2SO4. It was concentrated to half of its volume, the precipitated tan solid was filtered through a fritted funnel, rinsed with 2 mL of ether, collected and dried to give 1-(5-(4-amino-6-methyl-1,3,5-triazin-2-yl)-6-(6-chloro-5-methoxypyridin-3-ylamino)pyridin-3-yl)ethanone (90 mg, 64% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 12.63 (s, 1H), 9.29 (s, 1H), 9.03 (s, 1H), 8.47 (s, 1H), 8.30 (s, 1H), 8.06 (br., 1H), 7.90 (br., 1H), 3.96 (s, 3H), 2.60 (s, 3H), 2.47 (s, 3H). m/z (ESI, positive ion) 386.0 (M+H)+.
