実験手順

A suspension of 6-(3-fluoro-4-(2-iodothieno[3,2-b]pyridin-7-yloxy)phenyl)-1-phenyl-2,3-dihydroimidazo[1,2-a]pyrimidin-5(1H)-one (0.035 g, 0.060 mmol), 4-(morpholine-4-carbonyl)phenylboronic acid (0.017 g, 0.0721 mmol), Pd(PPh3)4 (0.003 g, 0.003 mmol) and lithium chloride (0.010 g, 0.240 mmol) in dioxane (1 mL) and 2M aqueous Na2CO3 (1 mL) was stirred at 100° C. for 50 minutes. The reaction mixture was cooled to room temperature and then partitioned between EtOAc and H2O. The layers were separated and the aqueous layer was re-extracted with EtOAc (1×). The combined organic layers were dried over Na2SO4, filtered and concentrated. The crude product was purified by flash column chromatography, eluting with 20:1 CH2Cl2/MeOH. The product was obtained (23 mg; 59%) as a pale yellow solid. 1H-NMR (400 MHz, CDCl3) δ 8.51 (d, 1H), 8.01 (s, 1H), 7.85-7.79 (m, 3H), 7.73-7.65 (m, 3H), 7.55-7.49 (m, 3H), 7.46 (m, 2H), 7.30 (m, 1H), 7.22, (m, 1H), 6.59 (dd, 1H), 4.33 (m, 4H), 3.95-3.36 (m, 8H).
