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% MeOHI CH2Cl2) gave the title compound (0.33 g, 52%) as a colorless solid: MS (ES) mnle 320.2 (M+H)+. Anal. Calcd for C20H21N30.0.4H2O: C, 73.57; H, 6.72; N, 12.86. Found: C, 73.94; H, 6.92; N, 12.50.
