Vorschrift

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-benzodioxol-5-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 2.04 (s, 3H), 2.32 (s, 3H), 4.69 (d, J=4.2 Hz, 2H), 5.76 (bs, 1H), 5.95 (s, 2H), 6.22 (s, 1H), 6.67-7.75 (m, 2H), 7.14 (t, J=6.4 Hz, 1H), 7.21 (s, 1H), 7.32 (d, J=7.8 Hz, 1H), 7.60 (t, J=7.6 Hz, 1H), 8.56 (d, J=3.6 Hz, 1H); MS (ESI) m/z 350.7 (M+1)+.
