Procedure

EDC (0.383 g, 2.0 mmole) was added to a solution of (E)-3-(6-aminopyridin-3-yl)acrylic acid (0.328 g, 2.0 mmole), 3-methyl-2-(methylaminomethyl)indene hydrochloride (0.420 g, 2.0 mmole), HOBt.H2O (0.306 g, 2.0 mmole), and triethylamine (0.57 mL, 4.0 mmole) in anhydrous DMF (18 mL) at RT. The reaction was stirred overnight and concentrated in vacuo. The residue was diluted with 5% NaHCO3 and extracted with CH2Cl2. The combined organic extracts were washed with brine and dried over MgSO4. Flash chromatography on silica gel (3% MeOH/CH2Cl2) gave the title compound (0.33 g, 52%) as a colorless solid: MS (ES) m/e 320.2 (M+H)+. Anal. Calcd for C20H21N3O.0.4H2O: C, 73.57; H, 6.72; N, 12.86. Found: C, 73.94; H, 6.92; N, 12.50.
