Procedure

Following general procedure I, 1-(4,6-dichloro-1,5-naphthyridin-3-yl)ethanone (170 mg, 0.71 mmol) was reacted with 6-[2-(dimethylamino)ethoxy]pyridin-3-amine (160 mg, 0.90 mmol) to afford the desired product (120 mg, 44%) as a light brown solid: 1H NMR (500 MHz, CDCl3) δ 11.63 (br s, 1H), 9.08 (s, 1H), 8.11 (d, J=8.8 Hz, 1H), 7.99 (d, J=2.7 Hz, 1H), 7.47 (d, J=8.7 Hz, 1H), 7.41 (dd, J=8.8, 2.8 Hz, 1H), 6.80 (d, J=8.7 Hz, 1H), 4.46 (t, J=5.6 Hz, 2H), 2.76 (t, J=5.6 Hz, 2H), 2.74 (s, 3H), 2.36 (s, 6H); ESI MS m/z 386 [M+H]+
