Versuchsvorschrift
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 (2,5-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 light-yellow solid. 1H NMR (300 MHz, CDCl3) δ ppm 2.09 (s, 3H), 2.35 (s, 3H), 4.75 (d, J=4.8 Hz, 2H), 5.96 (bs, 1H), 6.656-6.62 (m, 1H), 6.67 (bs, 1H), 7.01 (m, 1H), 7.16 (t, J=5.4 Hz, 1H), 7.37 (d, J=7.8 Hz, 1H), 7.62 (t, J=7.8 Hz, 1H), 8.29 (bs, 1H), 8.59 (d, J=3.4 Hz, 1H); MS (ESI) m/z 342.7 (M+1)+.
