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 1,3,4-thiadiazol-2-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, DMSO-d6) δ ppm 2.10 (s, 3H), 2.25 (s, 3H), 4.68 (d, J=2.0 Hz, 2H), 7.18-7.51 (m, 3H), 7.70 (t, J=7.8 Hz, 1H), 8.50 (s, 1H), 9.01 (s, 1H), 10.93 (bs, 1H); MS (ESI) m/z 314.1 (M+1)+.
