Procedure
The title compound was prepared from 2-amino-4-(imidazo-[1,2-a]pyridin-3-yl)pyrimidine and 4-bromo-3′-chlorobenzophenone following the general method of Example 2. The crude product was purified by column chromatography on silica gel using chloroform/ethanol, 99:1, as the eluent affording 51 mg (21% yield) of the title compound as a yellow solid: mp 194.7-196.7° C.; 1H NMR (400 MHz, DMSO-d6) δ 10.26 (s, 1 H), 10.17 (d, J=7.0 Hz, 1 H), 8.69 (s, 1 H), 8.54 (d, J=5.4 Hz, 1 H), 8.01 (d, J=8.7Hz, 2 H), 7.83-7.79 (m, 3 H), 7.76-7.72 (m, 2 H), 7.70-7.66 (m, 1 H), 7.62-7.59 (m, 1 H), 7.56-7.51 (m, 2 H), 7.21 (t, J=6.9 Hz, 1 H); 13C NMR (400 MHz, DMSO-d6) δ 193.2, 159.3, 157.7, 157.4, 148.4, 145.7, 140.4, 139.4, 133.7, 132.0, 131.8, 130.8, 129.8, 129.1, 129.0, 128.3, 127.6, 121.3, 118.3, 117.8, 114.3, 108.8; MS (ESP) m/z 426 (M+1).
