Embodiment 1
[0028] Add N-2-[[2-(dimethylamino)ethyl]methylamino]-4-methoxy-5-[[4-(1-methyl-1H-indole- 3-yl)-2-pyrimidinyl]amino]aniline (4.45g, 0.010mol), add acrylic acid (0.86g, 0.012mol), HY molecular sieves (0.44g, 0.002mol), isopropanol (32mL, 7.2ml / g), heated to 35°C with microwave, reacted for 4h, dried over anhydrous sodium sulfate, and finally removed the solvent by rotary evaporation to obtain 4.07g of a foamy off-white solid with a yield of 81.6%.
Embodiment 2
[0030] Add N-2-[[2-(dimethylamino)ethyl]methylamino]-4-methoxy-5-[[4-(1-methyl-1H-indole- 3-yl)-2-pyrimidinyl]amino]aniline (4.45g, 0.010mol), add acrylic acid (0.86g, 0.012mol), HY molecular sieves (0.66g, 0.003mol), isopropanol (32mL, 7.2ml / g), microwave heated to 35°C, reacted for 4 hours, dried over anhydrous sodium sulfate, and finally removed the solvent by rotary evaporation to obtain 4.88 g of a foamy off-white solid with a yield of 97.9%.
Embodiment 3
[0032] Add N-2-[[2-(dimethylamino)ethyl]methylamino]-4-methoxy-5-[[4-(1-methyl-1H-indole- 3-yl)-2-pyrimidinyl]amino]aniline (4.45g, 0.010mol), add acrylic acid (0.86g, 0.012mol), HY molecular sieves (0.66g, 0.003mol), isopropanol (32mL, 7.2ml / g), heated to 30°C with microwave, reacted for 4h, dried over anhydrous sodium sulfate, and finally removed the solvent by rotary evaporation to obtain 4.78g of a foamy off-white solid with a yield of 95.9%.
