Reaction Steps

Following general procedure II, 1-(6-chloro-4-{4-[2-(dimethylamino)ethyl]phenylamino}-1,5-naphthyridin-3-yl)ethanone (40 mg, 0.11 mmol) was reacted with 2-chloro-6-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (41 mg, 0.15 mmol) followed by formation of the dihydrochloride salt to afford the desired product (13 mg, 22%) as an orange solid: 1H NMR (500 MHz, CD3OD) δ 9.29 (s, 1H), 8.42 (d, J=9.1 Hz, 1H), 8.32 (d, J=9.0 Hz, 1H), 7.44 (d, J=8.5 Hz, 2 H), 7.41-7.35 (m, 3H), 7.11 (br s, 1H), 3.43-3.36 (m, 2H), 3.23-3.13 (m, 2H), 2.98 (s, 6H), 2.80 (s, 3H); ESI MS m/z 479 [M+H]+; HPLC>99% (AUC), tR=9.67 min.
