Following general procedure F, 1-(6-bromo-4-(trans-4-(2-(dimethylamino)ethyl)cyclohexyl amino)quinolin-3-yl)ethanone (4.8 g, 11.5 mmol) was reacted with 2,6-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (3.8 g, 13.1 mmol) to obtain the free base. The purified product was suspended in methanol (100 mL) after which HCl (125 mL, 1.25 M in methanol) was added to form a solution. The solution was concentrated to ˜50 mL and the resultant solid was filtered, washed with methanol, and dried to obtain desired product (3.8 g, 58% over two steps) as a yellow solid: 1H NMR (300 MHz, CD3OD) δ 9.10 (s, 1H), 8.50 (s, 1H), 8.27 (dd, J=8.8, 1.8 Hz, 1H), 7.97 (d, J=8.8 Hz, 1H), 7.73 (s, 2H), 4.55-4.48 (m, 1H), 3.27-3.15 (m, 2H), 2.90 (s, 6H), 2.74 (s, 3H), 2.42 (br d, J=12.3 Hz, 2H), 2.04 (br d, J=12.9 Hz, 2H), 1.84-1.65 (m, 4H), 1.63-1.56 (m, 1H), 1.34 (q, J=12.3 Hz, 2H); ESI MS m/z 500 [C27H31Cl2N3O2+H]+; HPLC>99% (AUC), tR=6.87 min.
