実験手順

(E)-3-(3-Acetoxy-4-methoxyphenyl)acrylic acid (0.099 g, 0.420 mmol) was suspended in dry THF (8 ml). SOCl2 (0.037 ml, 0.504 mmol) was added and the mixture was stirred at RT for 1 h. The solvent was evaporated to dryness and the residue was dissolved in dry THF (8.00 ml). TEA (0.059 ml, 0.420 mmol) and 1-(3-methyl-3H-imidazol-4-ylmethyl)-1H-indol-7-ylamine (0.095 g, 0.420 mmol) were added. The mixture was stirred at RT for 18 hrs, heated at reflux for 5 hrs and then at RT for 48 hrs. The solvent was removed in vacuo and the residue was partitioned between EtOAc (10 ml) and H2O (2×10 ml). Organic phase was dried over sodium sulphate and concentrated to dryness. The crude was charged onto a SCX cartridge and eluted firstly with MeOH and then with NH3/MeOH. The title (E)-3-(3-hydroxy-4-methoxy-phenyl)-N-[1-(3-methyl-3H-imidazol-4-ylmethyl)-1H-indol-7-yl]-acrylamide (56 mg) was obtained after column chromatography (eluent: DCM 100% to DCM/MeOH 98:2).
