Product 1

HCID 71738336N4-cyclohexyl-5,6-dimethyl-N2-[(1S)-1-phenylethyl]pyrimidine-2,4-diamine

Procedure

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 [(1S)-1-phenylethyl]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 light-yellow solid. 1H NMR (300 MHz, DMSO-d6) δ ppm 1.03-1.87 (m, 16H), 2.13 (s, 3H), 3.80 (s, 1H), 4.95-5.02 (m, 1H), 6.73 (s, 1H), 7.14-7.41 (m, 5H), 8.38 (s, 1H); MS (ESI) m/z 325.8 (M+1)+.
