実験手順

To a stirred solution of 1,4-dimethyl-3-(methylaminomethyl)-1H-indole (188.2 mg, 1 mmole) and (E)-3-(6-aminopyridin-3-yl)acrylic acid (164 mg, 1 mmole) in dry DMF (12 mL) containing dry Et3N (4 mL) was added HOBt.H2O (153 mg, 1 mmole) and EDC (191.8 mg, 1 mmole). The reaction was stirred overnight under argon at ambient temperature, then was concentrated in vacuo. The residue was partitioned between EtOAc and 5% NaHCO3 solution, and the layers were separated. The organic layer was washed with brine, dried (MgSO4), filtered, and concentrated. Flash chromatography on silica gel afforded the title compound (120 mg, 36%) as a white solid: MS (ES) m/e 335.2 (M+H)+. Anal. Calcd for C20H22N4O. 0.25 H2O:C, 70.88; H, 6.69; N, 16.53. Found: C, 71.11; H, 6.72; N, 16.36.
