反応手順

A mixture of 2-chloro-5-methyl-pyrimidin-4-ylamine (0.40 g, 2.8 mmol) and 4-morpholin-4-ylmethyl-phenylamine (0.60 g, 3.1 mmol) in acetic acid (15 mL) was heated at 70° C. for 17 h. After cooling to room temperature, the mixture was 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 brown syrup (0.70 g, 83%). It was used in the next step without purification. MS (ES+): m/z 300 (M+H)+.
