To a stirred solution of 2-chloro-N-cyclohexyl-5,6-dimethylpyrimidin-4-amine (0.1 g, 0.40 mmol) and (pyridin-2-ylmethyl)amine (0.04 g, 0.400 mmol) in acetonitrile (5 mL) was added a 3.5 M solution of hydrogen chloride in dioxane (0.2 mL). The resulting mixture was irradiated in CEM Focused Microwave™ Synthesis System at 160° C. for 120 minutes. The resulting mixture was cooled to ambient temperature. The formed precipitate was collected by filtration and dried to yield 0.07 g (48.2%) of the titled compound as the hydrochloride salt. 1H NMR (300 MHz, DMSO-d6) δ ppm 0.99-1.03 (m, 2H), 1.13 (d, J=12.63 Hz, 1H), 1.20-1.26 (m, 2H), 1.51-1.59 (m, 2H), 1.60-1.63 (m, 3H), 1.89 (s, 3H), 2.24 (s, 3H), 3.70 (s, 1H), 4.62 (d, J=5.10 Hz, 2H), 7.24 (dd, J=7.25, 4.84 Hz, 1H), 7.31 (d, J=7.79 Hz, 1H), 7.58 (d, J=7.72 Hz, 1H, 7.74 (t, J=7.66 Hz, 1H), 8.1 (s, 1H), 8.50 (d, J=4.84 Hz, 1H); MS (ESI) m/z 312.3 (M+1)+.
