反応手順
4-(2-methoxyethoxy)-2-nitroaniline (0.6 g, 2.830 mmol) and 6-chloro-N-methylpyrimidin-4-amine (0.404 g, 2.830 mmol) were taken in 10 mL of dry toluene in a seal tube under Argon atmosphere at room temperature. The Argon gas purging was continued for additional 5-10 min. Then Cs2CO3 (2.3 g, 7.075 mmol, 2.5 eq) and Xantphos (0.490 g, 0.849 mmol) were added and the resulting reaction mixture was purged with argon gas for 5 min, followed by Pd2(dba)3 (0.518 g, 0.566 mmol) was added. The argon gas purging was continued for additional 5 min before sealing the reaction vial. Then the reaction mixture was heated at 100° C. for 7 h. After completion of the reaction by TLC (DCM:MeOH, 98:2), reaction mass was filtered through celite and the filtrate was evaporated under vacuum to get a crude residue. The crude residue was purified by column chromatography on silica gel to afford the title compound (0.93 g, yield: 70%); MS (ESI): 320.3 [M+H]+.
