反応手順

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 bicyclo[2.2.1]hept-2-ylamine 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 (300 MHz, DMSO-d6) δ ppm 0.80-0.94 (m, 1H), 0.98-1.06 (m, 1H), 1.10-1.19 (m, 1H), 1.26-1.36 (m, 2H), 1.48-1.56 (m, 1H), 1.65-1.77 (m, 1H), 1.93 (s, 3H), 2.07 (s, 3H), 2.12-2.20 (m, 1H), 2.22-2.30 (m, 1H), 2.50-2.58 (m, 1H), 3.70-3.80 (m, 1H) 4.42-4.51 (m, 2H), 7.20-7.27 (m, 1H) 7.50-7.58 (m, 1H), 7.68-7.80 (m, 1H), 8.65 (d, J=4.92 Hz, 1H); MS (ESI) m/z 324.0 (M+1)+.
