Reaction Steps

Following general procedure F, 1-(6-bromo-4-(4-((4-methylpiperazin-1-yl)methyl)phenylamino)quinolin-3-yl)ethanone (6.0 g, 13.0 mmol) was reacted with 2,6-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (4.2 g, 15.0 mmol) to obtain the free base. The purified product was suspended in dichloromethane/methanol (1:1, 200 mL) after which HCl (36 mL, 1.25 M in methanol) was added to form a solution. The solution was concentrated to dryness and the resultant solid was triturated with dichloromethane. The mixture was filtered, washed with dichloromethane, and dried to obtain desired product (5.2 g, 66% over two steps) as a yellow solid: 1H NMR (300 MHz, CD3OD) δ 9.30 (s, 1H), 8.15 (dd, J=8.8, 1.9 Hz, 1H), 7.99 (d, J=8.8 Hz, 1H), 7.73 (d, J=2.0 Hz, 1H), 7.62 (d, J=8.0 Hz, 2H), 7.46 (d, J=8.0 Hz, 2H), 7.10 (s, 2H), 3.81 (s, 2H), 3.55-3.31 (m, 2H), 3.29-2.89 (m, 4H), 2.89 (s, 3H), 2.82 (s, 3H), 2.80-2.35 (m, 2H); APCI MS m/z 535 [C29H28Cl2N4O2+H]+; HPLC>99% (AUC), tR=7.89 min.
