Procedure

Phthalic anhydride (0.81 g, 5.48 mmole) was added to a solution of (E)-3-(6-aminopyridin-3-yl)-N-methyl-N-(1-methyl-1H-indol-2-ylmethyl)acrylamide (0.44 g, 1.37 mmole) and sodium bicarbonate (0.58 g, 6.85 mmole) in THF (70 mL) at RT, and the reaction was heated at reflux under nitrogen. After 48 hr, the reaction was concentrated in vacuo and the residue was purified by flash chromatography on silica gel (ethyl acetate). The title compound (0.21 g, 33%) was obtained as a white solid: MS (ES) m/e 451 (M+H)+.
