Procedimiento

EDC (0.56 g, 2.93 mmole) was added to a solution of (E)-3-(6-aminopyridin-3-yl)acrylic acid (0.48 g, 2.93 mmole), 1-ethyl-3-(methylaminomethyl)-1H-indole (0.50 g. 2.66 mmole), HOBt H2O (0.40 g, 2.93 mmole) and diisopropylethylamine (0.93 mL, 5.32 mmole) in DMF (30 mL) at RT. The reaction was stirred overnight then was concentrated in vacuo. The residue was diluted with water and extracted with ethyl acetate. The combined organic extracts were washed with brine and dried over Na2SO4. Flash chromatography on silica gel (10% MeOH/CHCl3) gave title compound (0.46 g, 52%) as a yellow solid after drying in vacuo: MS (ES) m/e 335 (M+H)+.
