Procedure

To a solution of (E)-3-(2-oxo-2,3-dihydro-1H-indol-5-yl)acrylic acid hydrochloride salt (0.50 g, 2.1 mmole), hydroxybenzotriazole monohydrate (0.31 g, 2.3 mmole), diisopropylethylamine (0.80 mL, 4.6 mmole), and 2-methyl-3-(methylaminomethyl)indole (0.40 g, 2.3 mmole) in DMF (50 mL) at RT was added EDC (0.46, 2.3 mmole). After 12 hr the reaction solution was concentrated under vacuum and the residue was purified by flash chromatography on silica gel (9:1 CHCl3/CH3OH containing 5% NH4OH) to give the title compound (0.66 g, 88%) as a light yellow solid: MS (ES) m/e 361 (M+H)+.
