实验过程
Following general procedure D, (R)-tert-butyl 1-(5-(6-bromo-3-(cyclopropanecarbonyl)quinoline-4-ylamino)pyridin-2-yl)piperidin-3-ylcarbamate (100 mg, 0.17 mmol) was reacted with 2-chloro-6-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (71 mg, 0.26 mmol) to obtain the protected intermediate which was subjected to general procedure A-2 to afford the desired product (33 mg, 37% over 2 steps) as an orange-yellow solid 1H NMR (500 MHz, MeOD+TFA-d) δ 9.41 (s, 1H), 8.28-8.14 (m, 2H), 8.05 (br s, 1H), 8.00 (d, J=8.8 Hz, 1H), 7.65 (dd, J=9.1, 2.8 Hz, 1H), 7.16-7.04 (m, 3H), 4.53 (d, J=11.6 Hz, 1H), 3.99 (dt, J=13.7, 4.0 Hz, 1H), 3.40-3.21 (m, 3H), 2.86 (br s, 3H), 2.23-2.15 (m, 1H), 1.98-1.89 (m, 1H), 1.79-1.65 (m, 2H), 1.27-1.16 (m, 4H). ESI MS m/z 532 [C29H27ClFN5O2+H]+ HPLC>99.0% (AUC), tR=10.77 min.
