47% | With sodium carbonate;(1,1'-bis(diphenylphosphine)ferrocene)palladium(0); In DMF (N,N-dimethyl-formamide); water; toluene; at 80℃; for 20h; | A mixture of (E)-2- PHENYLETHENYLBORONIC acid (0.93 g, 6.2 MMOL), 4-CHLORO-5-IODOPYRIMIDINE (1.5 g, 6.2 MMOL), 2M sodium carbonate solution (1.5 mL) and 1,1'- bis (DIPHENYLPHOSPHINO) ferrocene PALLADIUM (II) (0.39 g) in dimethylformamide : toluene 1: 2 (15 mL) was heated at 80C for 20 h. The reaction mixture was partitioned between DICHLOROMETHANE and water. The DICHLOROMETHANE layer was dried, concentrated, and chromatographed on silica gel, eluting with ethyl acetate: hexane 1: 9 to give the title compound (0.61 g, 47%). 1H NMR (400 MHz; DMSO-d6) O 7.22 (d, J=16 Hz, 1H), 7.33-7. 42 (m, 3H), 7.54 (d, J=16 Hz, 1H), 7.63 (d, J=8 Hz, 2H), 8.89 (s, 1H), 9.22 (s, 1H) ; ESIMS : 217 (M+H) + |

87% | With potassium carbonate;tetrakis(triphenylphosphine) palladium(0); In 1,4-dioxane; water; at 100℃; | To a hot (100 0C) solution of intermediate A.ii (18.5 g, 81.8 mmol), K2CO3 (14.7 g, 106 mmol), trans-2-phenylboronic acid (13.7 g, 90 mmol) in dioxane (320 mL) and water (80 mL) was added Pd(PPh3 )4 (4.77 g, 5 mol%). The resulting mixture was stirred at 1000C over night. After cooling, the reaction mixture was diluted with water (300 mL). The volatiles were removed in vacuo and the residue was taken up in EA (300 mL). The two layers were separated and the aq. layer was extracted one more with EA (300 mL). The combined org. layers were washed with brine, dried over MgSO4, filtered and <n="39"/>concentrated to dryness. The residue was chromatographed (EA-Hept 1 :2) to afford the title compound as a yellow solid (17.79 g, 87% yield).1H NMR (CDCl3) delta: 8.89 (d, J = 4.6 Hz, IH); 8.16 (dd, J = 9.5, 5.5 Hz, IH); 7.83 (dd, J = 2.7, 9.5 Hz, IH); 7.70-7.63 (m, 4H); 7.55-7.34 (m, 5H). |

The mixture is then stirred at 110° C. for 24 hours. The reaction mixture is cooled to room temperature and poured into H2O. A gray crude product is obtained after filtration and washing with n-hexane. The crude product is purified by silicagel column chromatography with CH2Cl2, which result in a white solid (71percent yield, mp.: 226° C.). 1H-NMR (CDCl3, ppm): 7.26-7.30 (m, 6H), 7.39 (t, 4H), 7.54-7.58 (m, 6H), 7.65 (dd, 2H), 8.12 (d, 2H) |

The reaction mixture was purged with argon for 5 min and then heated at 95 C. for 16 h. The reaction solution was cooled to room temperature, diluted with ethyl acetate, washed with water (2*) and brine, dried over sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by flash column chromatography (silica gel hexanes/ethyl acetate 95:5 to 60:40) to afford the title compound (0.51 g, 96%) as a yellow solid: 1H NMR (500 MHz, CDCl3) delta 8.47 (d, J=5.0 Hz, 1H), 7.92 (d, J=16.0 Hz, 1H), 7.61-7.58 (m, 2H), 7.42-7.35 (m, 3H), 7.01 (d, J=16.0 Hz, 1H), 6.94 (d, J=5.0 Hz, 1H), 4.07 (s, 3H). |
