Reaction Steps
Following general procedure D, tert-butyl 1-(5-(6-bromo-3-(cyclopropanecarbonyl)quinolin-4-ylamino)pyridin-2-yl)pyrrolidin-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 (17 mg, 18% over 2 steps) as a orange-yellow solid: 1H NMR (500 MHz, CD3OD+TFA-d) δ 9.38 (s, 1H), 8.31 (dd, J=8.8, 1.9 Hz, 1H), 8.25 (m, 2H), 8.05 (d, J=8.8 Hz, 1H), 7.89 (dd, J=9.3, 2.6 Hz, 1H), 7.13 (d, J=2.1 Hz, 1H), 7.06 (dd, J=9.3, 0.8 Hz, 1H), 6.90 (s, 1H), 4.15 (dt, J=11.2, 5.7 Hz, 1H), 4.04 (dd, J=11.9, 6.5 Hz, 1H), 3.94 (s, 3H), 3.86 (m, 1H), 3.76 (m, 2H), 2.83 (dt, J=12.1, 6.3 Hz, 1H), 2.60 (dt, J=21.4, 6.6 Hz, 1H), 2.31 (td, J=13.4, 5.7 Hz, 1H), 1.21 (m, 4H); ESI MS m/z 529 [C29H28ClN5O3+H]+; HPLC 99.6% (AUC), tR=9.97 min.
