実験手順
Following general procedure D, tert-butyl 1-(5-(6-bromo-3-(cyclopropanecarbonyl)quinolin-4-ylamino)pyridin-2-yl)piperidin-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 (74 mg, 0.27 mmol) to obtain the protected intermediate which was subjected to general procedure A-2 to afford the desired product (39 mg, 41% over 2 steps) as a orange-red solid: 1H NMR (500 MHz, CD3OD+TFA-d) δ 9.40 (s, 1H), 8.22 (m, 2H), 8.09 (s, 1H), 8.02 (d, J=8.8 Hz, 1H), 7.71 (dd, J=9.2, 2.8 Hz, 1H), 7.15 (m, 3H), 4.51 (d, J=10.3 Hz, 1H), 4.02 (m, 1H), 3.37 (m, 1H), 2.85 (tt, J=7.7, 4.6 Hz, 1H), 2.20 (m, 1H), 1.97 (m, 1H), 1.75 (m, 2H), 1.22 (m, 4H); ESI MS m/z 532 [C29H27ClFN5O2+H]+; HPLC 99.0% (AUC), tR=10.81 min.
