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 (3,5-difluorophenyl)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 2.07 (s, 3H), 2.34 (s, 3H), 4.73 (d, J=3.1 Hz, 2H), 5.93 (bs, 1H), 6.39-6.49 (m, 2H), 7.13-7.22 (m, 3H), 7.34 (d, J=7.8 Hz, 1H), 7.63 (t, J=5.9 Hz, 1H), 8.59 (d, J=3.8 Hz, 1H); MS (ESI) m/z 342.7 (M+1)+.
