Procedure

A solution of 2-chloro-4-(methylamino)-7-phenyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-5-one (Preparation AN) (7 mg) and 4-(4-chloro-1H-imidazol-1-yl)-3-methoxyaniline (Preparation A) (7 mg) in THF (0.2 mL) and sulfuric acid (4 mg) was heated at 85° C. for 12 h. THF was removed in vacuo, and the residue was purified by reverse phase preparative to give the title compound (as its TFA salt) as a yellowish oil (9 mg). LC-MS (M+H)+=461.12. 1H NMR (500 MHz, CD3OD) δ ppm 7.80 (m), 7.1-7.4 (m), 4.50 (1H, m), 3.25 (1H, m), 2.56 (1H, m), 3.50 (3H, s), and 3.19 (3H, s).
