Reaction Steps

Following general procedure F, 1-(6-bromo-4-(6-(2-(dimethylamino)ethoxy)pyridin-3-ylamino)quinolin-3-yl)ethanone (5.0 g, 12.0 mmol) was reacted with 2,6-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (3.7 g, 13.0 mmol) to obtain the free base. The purified product was suspended in dichloromethane/methanol (1:1, 300 mL) after which HCl (30 mL, 1.25 M in methanol) was added to form a solution. The solution was concentrated to dryness to obtain desired product (5.2 g, 74% over two steps) as a yellow solid: 1H NMR (300 MHz, CD3OD) δ 9.27 (s, 1H), 8.29 (d, J=2.9 Hz, 1H), 8.20-8.10 (m, 1H), 8.06-7.96 (m, 1H), 7.87-7.77 (m, 2H), 7.20 (s, 2H), 7.17-7.08 (m, 1H), 4.81-4.71 (m, 2H), 3.64 (t, J=5.1 Hz, 2H), 3.01 (s, 6H), 2.80 (s, 3H); ESI MS m/z 511 [C26H24Cl2N4O3+H]+; HPLC>99% (AUC), tR=6.86 min.
