Procedure

Following general procedure I, 1-(4,6-dichloro-1,5-naphthyridin-3-yl)ethanone (250 mg, 1.0 mmol) was reacted with 3-[2-(pyrrolidin-1-yl)ethyl]aniline (240 mg, 1.3 mmol) to afford the desired product (230 mg, 57%) as a yellow solid: 1H NMR (500 MHz, CDCl3) δ 10.79 (br s, 1H), 8.99 (s, 1H), 8.16 (d, J=8.7 Hz, 1H), 7.52 (d, J=8.8 Hz, 1H), 7.29-7.20 (m, 1H), 7.07 (d, J=7.7 Hz, 1H), 7.03-6.96 (m, 2H), 2.85-2.77 (m, 2H), 2.72-2.66 (m, 2H), 2.59-2.49 (m, 4H), 2.53 (s, 3H), 1.84-1.74 (m, 4H); ESI MS m/z 395 [M+H]+
