実験手順
A mixture of 2-chloro-5-methyl-pyrimidin-4-ylamine (0.50 g, 3.5 mmol) and 4-(2-pyrrolidin-1-yl-ethoxy)-phenylamine (1.1 g, 5.3 mmol) in acetic acid (8 mL) was sealed in a microwave reaction tube and irradiated with microwave at 150° C. for 15 min. After cooling to room temperature, the cap was removed and the mixture concentrated. The residue was taken in water (30 mL) and neutralized with 10% NaOH solution until pH ˜10. The resulting aqueous layer was extracted with EtOAc (2×30 mL) and the combined organic layers washed with brine, dried over anhydrous Na2SO4 and filtered. The filtrate was concentrated to afford the title compound as a grey solid (0.80 g, 73%). It was used in the next step without purification. MS (ES+): m/z 314 (M+H)+.
