Reaction Steps

2-Chloro-N-methyl-7-(3,4,5-trifluorophenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-amine (100 mg, 0.319 mmol) was added to a solution of 6-(4-chloro-1H-imidazol-1-yl)-5-methoxypyridin-3-amine (107 mg, 0.478 mmol) in acetic acid (2 mL) and THF (2.000 mL). The reaction mixture was heated at 80° C. overnight. Partial formation of the desired product was observed. The reaction mixture was heated at 130° C. for 6 h. The crude reaction mixture was purified by preparative HPLC. The appropriate fractions were evaporated to afford N2-(6-(4-chloro-1H-imidazol-1-yl)-5-methoxypyridin-3-yl)-N4-methyl-7-(3,4,5-trifluorophenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine-2,4-diamine, TFA salt (12.9 mg, 0.021 mmol, 6.50% yield). LC-MS (M+H)+=502.2. 1H NMR (500 MHz, CDCl3) δ ppm 12.33 (1H, s), 8.75 (1H, s), 8.56 (1H, s), 7.61-7.89 (2H, m), 6.85-7.00 (2H, m), 5.62-5.79 (1H, m), 4.36-4.49 (1H, m), 4.02 (3H, s), 3.29 (3H, d, J=4.9 Hz), 2.88-2.98 (1H, m), 2.76-2.85 (2H, m), 2.21-2.38 (1H, m).
