4-Isopropylbenzylamine → N4-cyclohexyl-N2-(4-isopropylbenzyl)-5,6-dimethylpyrimidine-2,4-diamine

Participants

Reaction Steps

The titled compound was synthesized according to the general procedure described for preparation of N4-cyclohexyl-5,6-dimethyl-N2-(pyridin-2-ylmethyl)pyrimidine-2,4-diamine (Example 1) using (4-isopropylbenzyl)amine instead of (pyridin-2-ylmethyl)amine. The product 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 1.08 (d, J=15.04 Hz, 1H), 1.17 (d, J=6.72 Hz, 6H), 1.24-1.31 (m, 4H), 1.60 (s, 1H), 1.68 (t, J=11.95 Hz, 4H), 1.87 (s, 3H), 2.22 (s, 3H), 2.84 (t, J=13.90, 6.88 Hz, 1H), 3.89 (d, J=7.52 Hz, 1H), 4.48 (d, J=5.37 Hz, 2H), 7.14-7.28 (m, 4H), 7.55 (d, J=7.52 Hz, 1H), 8.06 (s, 1H), 12.69 (bs, 1H); MS (ESI) m/z 353.0 (M+1)+.
