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 [3-(trifluoromethoxy)phenyl]amine 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, CDCl3) δ ppm 2.09 (s, 3H), 2.35 (s, 3H), 4.73 (d, J=5.6 Hz, 2H), 6.08 (bs, 1H), 6.48 (bs, 1H), 6.88 (d, J=7.3 Hz, 1H), 7.16 (t, J=7.3 Hz, 1H), 7.22-7.34 (m, 3H), 7.62 (t, J=9.4 Hz, 1H), 7.75 (s, 1H), 8.57 (d, J=3.2 Hz, 1H); MS (ESI) m/z 390.7 (M+1)+.
