Reaktionsschritte

The titled compound was synthesized according to the procedure described for preparation of N4-cyclopentyl-5,6-dimethyl-N2-(pyridin-2-ylmethyl)pyrimidine-2,4-diamine (Example 29) using 2,3-dimethylcyclohexanamine instead of cyclopentanamine. The crude material 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 (400 MHz, CDCl3) δ ppm 0.75-0.76 (m, 3H), 0.85-0.95 (m, 3H), 1.55-1.74 (m, 8H), 1.86-1.97 (m, 4H), 2.07 (s, 3H), 3.10-3.18 (m, 1H), 4.43 (bs, 2H), 7.20-7.26 (m, 1H), 7.50-7.57 (m, 1H), 7.67-7.73 (m, 1H), 8.60-7.68 (m, 1H); MS (ESI) m/z 340.4 (M+1)+.
