To a stirred suspension of (6-methoxy-1H-indol-3-yl)(3,4,5-trimethoxyphenyl)methanone (0.69 g, 0.5 mmol) and K2CO3 in anhydrous DMF (2 ml) was added the solution of 1-(3-bromoprop-1-ynyl)-4-iodobenzene (0.150 g, 0.47 mmol) in anhydrous DMF (0.5 ml) and the resulting mixture was stirred at 50° C. for 2 h, diluted with saturated solution of NH4Cl (5 ml) and diluted to 30 ml with EtOAc. The organic layer was washed with H2O and dried over MgSO4 and filtered. The filtrate was evaporated to dryness and the residue was purified by FCC (SiO2), to give the desired product (0.079 g; 32%), as light yellow paste. 1H-NMR (CDCl3) 3.84 (s, 6H); 3.89 (s, 3H); 3.91 (s, 3H); 5.06 (s, 2H); 6.94 (d, 1H, J=2.06 Hz); 7.00 (dd, 1H, J=2.22, 7.1 (s, 2H); 8.75 Hz); 7.1 (d, 2H, J=8.27 Hz); 7.65 (d, 2H, J=8.42 Hz); 7.72 (s, 1H); 8.25 (d, 1H, J=8.78 Hz).
