Reaction Steps

To a stirred solution of (E)-3-(6amino-4-methylpyridin-3-yl)acrylic acid HCl salt (0.70 g, 3.3 mmole) in 1:1 DMF/CH2Cl2 (30 mL) was added Et3N (0.42 mL, 3 mmole), 1-methyl-2-(methylaminomethyl)indole (0.50 g, 2.9 mmole), HOBt.H2O (0.41 g, 3 mmole), and DCC (0.70 g, 3 mmole). After stirring at RT for 16 hr the reaction was concentrated under vacuum. The residue was taken up in ethyl acetate and filtered. The filtrate was washed with 1.0 N Na2CO3 then with brine, dried (Na2SO4), and concentrated under vacuum. Purification by flash chromatography on silica gel (4% methanol/CHCl3) gave the title compound (0.74 g, 74%) as a pale yellow solid: LCMS (ES) m/e 335.2 (M+H)+.
