3-Fluoro-2-methylaniline → N4-(3-fluoro-2-methylphenyl)-5,6-dimethyl-N2-(pyridin-2-ylmethyl)pyrimidine-2,4-diamine

Participants

Reaction Steps

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-fluoro-2-methylphenyl)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 1.94 (s, 3H), 2.06 (s, 3H), 2.14 (s, 3H), 4.32 (bs, 2H), 6.76 (bs, 1H), 6.86-6.95 (m, 1H), 7.01-7.13 (m, 3H), 7.17 (t, J=6.4 Hz, 1H), 7.63 (t, J=8.4 Hz, 1H), 7.75 (s, 1H), 8.43 (d, J=4.2 Hz, 1H); MS (ESI) m/z 338.2 (M+1)+.
