Reaction Steps

The titled compound was synthesized according to the general procedure described for preparation of N4-cyclohexyl-5,6-dimethyl-N2-(pyridin-2-ylmethyl)pyrimidine-2,4-diamine (Example 1) using [(4-ethylpyridin-2-yl)methyl]amine instead of (pyridin-2-ylmethyl)amine and 2-chloro-N-(4,4-difluorocyclohexyl)-5,6-dimethylpyrimidin-4-amine (Step A) instead of 2-chloro-N-cyclohexyl-5,6-dimethylpyrimidin-4-amine. The product was purified by crystallization from ethanol to afford the titled compound as the hydrochloride salt as a light-yellow solid. 1H NMR (300 MHz, DMSO-d6) δ ppm 1.16 (t, J=7.59 Hz, 3H), 1.57-1.1.89 (m, 11H) 2.25 (s, 3H) 2.62 (m, 2H) 3.95 (s, 1H) 4.64 (d, J=5.12 Hz, 2H) 7.17 (d, J=5.12 Hz, 1H) 7.24 (s, 1H) 7.64 (d, J=6.40 Hz, 1H) 8.31 (s, 1H) 8.40 (d, J=4.94 Hz, 1H) 12.58 (bs, 1H); MS (ESI) m/z 375.9 (M+1)+.
