Procedure

Following general procedure D, tert-butyl 1-(5-(6-bromo-3-propionylquinolin-4-ylamino) pyridin-2-yl)pyrrolidin-3-ylcarbamate (100 mg, 0.18 mmol) was reacted with 2-chloro-6-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (76 mg, 0.28 mmol) to obtain the protected intermediate which was subjected to general procedure A-2 to afford the desired product (34 mg, 37% over two steps) as a yellow solid: 1H NMR (500 MHz, CD3OD+TFA-d) δ 9.29 (s, 1H), 8.29-8.18 (m, 2H), 8.06-7.99 (m, 2H), 7.82 (dd, J=9.1, 2.6 Hz, 1H), 7.16-7.10 (m, 1H), 7.07 (s, 1H), 6.97 (d, J=9.1 Hz, 1H), 4.17-4.08 (m, 1H), 4.06-3.98 (m, 1H), 3.90-3.81 (m, 1H), 3.79-3.70 (m, 2H), 3.27-3.19 (m, 2H), 2.64-2.53 (m, 1H), 2.35-2.25 (m, 1H), 1.26 (t, J=7.1 Hz, 3H); ESI MS m/z 506 [C27H25ClFN5O2+H]+; HPLC>99% (AUC), tR=10.75 min.
