Procedure

Following general procedure D, tert-butyl 1-(5-(6-bromo-3-(cyclopropanecarbonyl)quinoline-4-ylamino)pyridin-2-yl)piperidin-3-ylcarbamate (100 mg, 0.18 mmol) was reacted with 2-chloro-6-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (77 mg, 0.27 mmol) to obtain the protected intermediate which was subjected to general procedure A-2 to afford the desired product (39 mg, 40% over 2 steps) as a yellow-orange solid: 1H NMR (500 MHz, CD3OD+TFA-d) δ 9.39 (s, 1H), 8.25 (s, 1H), 8.14 (s, 1H), 8.05 (s, 1H), 7.77 (s, 1H), 7.21 (s, 1H), 7.02 (s, 1H), 6.87 (s, 1H), 4.49 (s, 1H), 4.02 (s, 1H), 3.93 (s, 3H), 2.84 (s, 1H), 2.22 (s, 1H), 1.97 (s, 1H), 1.75 (s, 2H), 1.23 (s, 4H); ESI MS m/z 544 [C30H30ClN5O3+H]+; HPLC 99.7% (AUC), tR=10.68 min.
