Procedure
Following general procedure II, 1-(6-chloro-4-{6-[2-(dimethylamino)ethoxy]pyridin-3-ylamino}-1,5-naphthyridin-3-yl)ethanone (50 mg, 0.13 mmol) was reacted with 2-chloro-6-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (53 mg, 0.20 mmol) followed by formation of the dihydrochloride salt to afford the desired product (40 mg, 54%) as an orange solid: 1H NMR (500 MHz, CD3OD) δ 9.35 (br s, 1H), 8.45 (d, J=9.0 Hz, 1H), 8.37 (d, J=8.9 Hz, 1H), 8.28 (d, J=2.6 Hz, 1H), 7.76 (dd, J=8.8, 2.7 Hz, 1H), 7.35 (br s, 1H), 7.10 (br s, 1H), 7.01 (d, J=8.8 Hz, 1H), 4.74-4.68 (m, 2H), 3.66-3.60 (m, 2H), 3.02 (s, 6H), 2.84 (s, 3H); ESI MS m/z 496 [M+H]+; HPLC 98.3% (AUC), tR=9.47 min.
