Reaction Steps

Following general procedure F, 1-(6-bromo-4-(trans-4-(pyrrolidin-1-ylmethyl)cyclohexylamino)quinolin-3-yl)ethanone (6.0 g, 14.0 mmol) was reacted with 2,6-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (4.4 g, 15.0 mmol) to obtain the free base. The purified product was suspended in dichloromethane/methanol (1:1, 200 mL) after which HCl (35 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 (4.9 g, 60% over two steps) as a yellow solid: 1H NMR (300 MHz, CD3OD) δ 9.10 (s, 1H), 8.47 (d, J=2.1 Hz, 1H), 8.26 (dd, J=8.8, 1.8 Hz, 1H), 7.98 (d, J=8.8 Hz, 1H), 7.73 (s, 2H), 4.55-4.45 (m, 1H), 3.70 (br s, 2H), 3.20-3.04 (m, 4H), 2.74 (s, 3H), 2.45 (d, J=12.6 Hz, 2H), 2.17-1.94 (m, 7H), 1.89-1.70 (m, 2H), 1.46-1.27 (m, 2H); APCI MS m/z 512 [C28H31Cl2N3O2+H]+; HPLC>99% (AUC), tR=8.69 min.
