Procedure

EDC (203 mg, 1.06 mmole) was added to a solution (E)-3-(5,6,7,8-tetrahydro-1,8-naphthyridin-3-yl)acrylic acid (180 mg, 0.88 mmole), 1-methyl-2-(methylaminomethyl)-1H-indole (185 mg, 1.06 mmole), HOBt.H2O (143 mg, 1.06 mmole), and Et3N (0.31 mL, 2.2 mmole) in dry DMF (5 mL) at RT. After 18 hr the mixture was concentrated. Flash chromatography on silica gel (10% EtOH/EtOAc) gave the title compound (222 mg, 70%) as a yellow solid: 1H NMR (400 MHz, DMSO-d6) δ 7.99-6.82 (m, 8H), 6.40 (s, 1H), 4.82 (s, 2H), 3.67 (m, 2H), 3.29 (m, 3H), 3.07 (m, 3H), 2.73 (m, 2H), 1.77 (m, 2H); for minor rotomer δ 6.16 (s, 1H), 5.00 (s, 2H); MS (ES) m/e 361 (M+H)+.
