Procedure
Under N2, the mixture of Example 7A (168 mg, 0.7 mmol), 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-indole (ref. WO02055517, 170 mg, 0.7 mmol), Pd2(dba)3 (Aldrich, 19 mg, 0.02 mmol), 1,3-bis(2,6-iso-propylphenyl)imidazolium chloride (Strem Chemicals, 26 mg, 0.06 mmol) and aqueous Na2CO3 (2 M, 1 mL) in toluene (10 mL) was stirred at 110° C. overnight, After the reaction was complete, it was cooled down to room temperature and diluted with EtOAc (30 mL). The mixture was then washed with brine (2×5 mL) and the title compound was purified by chromatography (SiO2, CH2Cl2:MeOH:NH3.H2O, 90:10:1, Rf. 0.10) as solid (45 mg, yield, 20%). 1H NMR (300 MHz, CD3OD) δ 1.51-1.65 (m, 1H), 1.70-1.93 (m, 2H), 2.01-2.16 (m, 1H), 2.31-2.39 (m, 1H), 2.78-3.09 (m, 5H), 3.45-3.56 (m, 1H), 5.30-5.38 (m, 1H), 6.78 (dd, J=3.4, 1.0 Hz, 1H), 7.25 (t, J=7.8 Hz, 1H), 7.30 (d, J=9.5 Hz, 1H), 7.36 (d, J=3.1 Hz, 1H), 7.40 (dd, J=7.5, 1.0 Hz, 1H), 7.52 (dt, J=8.1, 1.0 Hz, 1H), 8.07 (d, J=9.2 Hz, 1H) ppm. MS (DCI/NH3): m/z 321 (M+H)+.
