Reaktionsschritte

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-(trifluoromethoxy)benzyl]amine instead of (pyridin-2-ylmethyl)amine. The product was purified by column chromatography eluting with mixture of chloroform/ethanol/20% water solution of ammonia (200:10:1), and then the final product was washed with diethyl ether to afford the titled compound as a white solid. 1H NMR (300 MHz, DMSO-d6) δ ppm 1.19-1.28 (m, 3H), 1.59 (d, J=13.59 Hz, 4H), 1.67 (s, 1H), 1.86 (s, 3H), 2.23 (s, 3H), 3.79 (s, 1H), 4.56 (d, J=5.04 Hz, 2H), 7.30 (d, J=8.11 Hz, 2H), 7.40-7.45 (m, 2H), 7.57 (d, J=7.23 Hz, 1H), 8.18 (t, J=5.26 Hz, 1H), 12.85 (bs, 1H); MS (ESI) m/z 394.8 (M+1)+.
