Procedure

To a suspension of (±)-5-chloro-7-methyl-4-(((tetrahydro-2H-pyran-2-yl)oxy)methyl)-1-tosyl-1H-indole (Example 47-D) (2.1 g, 4.8 mmol), vinylboronic anhydride pyridine complex (3.5 g, 14.5 mmol) and K2CO3 (6.7 g, 48.4 mmol) in toluene (10 mL)/H2O (4 mL) were added Pd(OAc)2 (0.22 g, 0.97 mmol) and S-Phos (CAS; 657408-07-6) (0.80 g, 1.9 mmol), and then the mixture was stirred at 90° C. under N2 atmosphere for 4 h. The reaction mixture was cooled to room temperature, diluted with CH2Cl2 and partitioned. The organic phase was washed with H2O and brine, dried over Na2SO4, and then filtered. Concentration of the filtrate gave a residue that was purified by SiO2 column chromatography (heptane/EtOAc=95/5 to 7/3) to give the title compound. 1H NMR (400 MHz, ACETONITRILE-d3) δ 7.78 (d, J=3.79 Hz, 1H), 7.58 (d, J=8.59 Hz, 2H), 7.26-7.38 (m, 3H), 7.13 (dd, J=11.12, 17.43 Hz, 1H), 6.95 (d, J=3.79 Hz, 1H), 5.70 (dd, J=1.26, 17.43 Hz, 1H), 5.31 (dd, J=1.26, 11.12 Hz, 1H), 4.93 (d, J=11.37 Hz, 1H), 4.72 (d, J=11.37 Hz, 1H), 4.56-4.66 (m, 1H), 3.78-3.92 (m, 1H), 3.35-3.57 (m, 1H), 2.57 (s, 3H), 2.35 (s, 3H), 1.56-1.75 (m, 2H), 1.38-1.56 (m, 4H).
