Reaction Steps

2-Chloro-N-methyl-7-(4-(trifluoromethoxy)phenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-amine (220 mg, 0.640 mmol) was added to a solution of 4-(4-chloro-1H-imidazol-1-yl)-3-methoxyaniline (215 mg, 0.960 mmol) in acetic acid (2 mL) and THF (2.000 mL). The reaction mixture was heated at 80° C. overnight. The crude reaction mixture was purified by preparative HPLC. The appropriate fractions were evaporated to afford N2-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-N4-methyl-7-(4-(trifluoromethoxy)phenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine-2,4-diamine (92 mg, 0.172 mmol, 26.8% yield). LC-MS (M+H)+=531.2. 1H NMR (500 MHz, CDCl3) δ ppm 7.93 (1H, s), 7.66 (1H, br s), 7.50 (1H, s), 7.10-7.23 (4H, m), 7.02 (2H, d, J=15.3 Hz), 6.83 (1H, d, J=8.2 Hz), 4.70-4.83 (1H, m), 4.13-4.28 (1H, m), 3.12 (3H, d, J=4.9 Hz), 2.74 (1H, br. s.), 2.65 (2H, d, J=8.2 Hz), 1.97-2.08 (1H, m), 1.25 (3H, s).
