実験手順

A solution of 2-chloro-7-(2,4-difluorophenyl)-N-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-amine (184.6 mg, 0.624 mmol) and 4-(4-chloro-1H-imidazol-1-yl)-3-methoxyaniline (140 mg, 0.624 mmol) in THF (1095 μL) and acetic acid (1095 μL) was heated 80° C. in a capped vial overnight. The solvent was evaporated in vacuum and the residue was partitioned between aqueous sodium bicarbonate solution and dichloromethane. The organic layer was separated and the aqueous layer was extracted with dichloromethane. the combined organic extracts were dried over anhydrous magnesium sulfate and filtered. The solvent was removed in vacuum and the residue was purified by column chromatography on silica gel to give N2-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-7-(2,4-difluorophenyl)-N4-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidine-2,4-diamine (179.6 mg, 0.372 mmol, 59.6% yield) as brown solid. LC-MS (M+H)+=483.1. 1H NMR (500 MHz, CDCl3) δ ppm 7.97 (1H, d, J=2.1 Hz), 7.49 (1H, d, J=1.5 Hz), 7.01-7.10 (2H, m), 7.00 (1H, d, J=1.5 Hz), 6.73-6.84 (3H, m), 4.44 (1H, s), 3.61 (3H, s), 3.11 (3H, d, J=4.9 Hz), 2.59-2.77 (2H, m), 1.95-2.05 (2H, m).
