反応手順

A mixture of 6-chloro-2-methylpyrimidin-4-ylamine (717 mg, 5.0 mmol) and ethanolamine (0.602 mL, 10.0 mmol) were heated at 250° C. in a microwave for 30 seconds. After cooling, the residue was dissolved in ethyl acetate, containing a small amount of methanol and was washed with brine. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure to afford the title compound as a white solid (334 mg, 40% yield). 1H NMR (400 MHz, DMSO-d6): δ 6.45 (br s, 1H), 5.98 (br s, 2H), 5.25 (s, 1H), 3.47 (t, J=6.0 Hz, 2H), 3.23-3.14 (m, 2H), 2.12 (s, 3H).
