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 (2-thienylmethyl)amine instead of (pyridin-2-ylmethyl)amine. The crude product was purified by crystallization from ethanol (10 mL) to afford the titled compound as the hydrochloride salt as a light-grey solid. 1H NMR (300 MHz, DMSO-d6) δ ppm 1.20-1.35 (m, 5H), 1.65-1.79 (m, 5H), 1.89 (s, 3H), 2.23 (s, 3H), 4.08 (bs, 1H), 4.71 (d, J=4.57 Hz, 2H), 6.96 (s, 1H), 7.05 (s, 1H), 7.40 (d, J=4.57 Hz, 1H), 7.70 (d, J=6.72 Hz, 1H), 8.07 (s, 1H); MS (ESI) m/z 317.7 (M+1)+.
