실험 절차

To a 50 mL round bottom flask, 4-(7-bromo-2-chloropyrido[3,2-d]pyrimidin-4-yl)morpholine (1.0 g, 0.00303 mol; prepared as described in Scheme 7A) and 5-formyl-2-furanylboronic acid (0.38 g, 0.00273 mol), sodium carbonate (0.64 g, 0.00606 mol) toluene (5 mL), EtOH (5 mL) and water (5 mL) were added. The reaction vessel was degassed with nitrogen for 5-10 min. To the same reaction mixture, Pd(PPh3)2Cl2 (0.106 g, 0.0001515 mol) was added and again degassed with nitrogen for 5-10 min. The reaction mixture was stirred at 90° C. for 2 h. The reaction mixture was cooled and diluted with chloroform. The organic layer was washed with water, brine and dried over sodium sulfate. The solvent was removed under the reduced pressure to afford the crude product. The crude product was purified using column chromatography (60-120 silica gel, chloroform) to yield the desired product as a yellow solid [0.48 g, 46%]. 1H NMR (300 MHz, CDCl3): δ 9.77 (s, 1H), 9.12 (d, J=2.1 Hz, 1H), 8.34 (d, J=2.1 Hz, 1H), 7.40 (d, J=3.6 Hz, 1H), 7.11 (d, J=3.6 Hz, 1H), 4.50 (brs, 4H), 3.91-3.88 (m, 4H); LC-MS (ESI): Calculated mass: 344.1; Observed mass: 345.0 (RT: 1.39 min).
