Procedure

A 10-mL microwave vial was charged with 4-chloro-2-(3-chlorophenyl)-6-cyclopropylpyrimidine (0.100 g, 0.38 mmol) and (4-aminophenyl)acetamide (0.113 g, 0.75 mmol) in NMP (3 mL). The resulting mixture was heated at 120° C. under microwave irradiation for 2 h. The reaction mixture was cooled, diluted with water (50 mL) affording a solid. The solid was isolated by filtration and purified by chromatography on silica using hexanes/ethyl acetate (10:0 to 0:10) as eluent to afford the title compound (0.107 g, 78%) as a white solid. MW=378.85. M.p. 174-176° C. 1H NMR (DMSO-d6, 500 MHz) δ 9.51 (s, 1H), 8.27-8.22 (m, 2H), 7.61 (d, J=8.0 Hz, 2H), 7.57-7.52 (m, 2H), 7.43 (br s, 1H), 7.25 (d, J=8.5 Hz, 2H), 6.85 (br s, 1H), 6.63 (s, 1H), 3.35 (s, 2H), 2.07-2.00 (m, 1H), 1.12-1.06 (m, 2H), 1.03-0.95 (m, 2H); ESI MS m/z 379 [M+H]+.
