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 5-methylisoxazol-3-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 2.06 (s, 3H), 2.35 (s, 3H), 4.75 (d, J=2.8 Hz, 2H), 5.92 (bs, 1H), 6.54 (s, 1H), 7.18 (m, 1H), 7.36 (d, J=7.8 Hz, 1H), 7.64 (t, J=7.5 Hz, 1H), 8.59 (d, J=4.0 Hz, 1H); MS (ESI) m/z 311.5 (M+1)+.
