Reaction Steps
Following general procedure D, tert-butyl 1-(5-(6-bromo-3-(cyclopropanecarbonyl)quinoline-4-ylamino)pyridin-2-yl)pyrrolidin-3-ylcarbamate (100 mg, 0.18 mmol) was reacted with 2,6-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (78 mg, 0.27 mmol) to obtain the protected intermediate which was subjected to general procedure A-2 to afford the desired product (23 mg, 24% over 2 steps) as a orange solid: 1H NMR (500 MHz, CD3OD+TFA-d) δ 9.35 (s, 1H), 8.33 (s, 1H), 8.30 (dd, J=8.8, 1.9 Hz, 1H), 8.28 (d, J=2.5 Hz, 1H), 8.11 (d, J=8.8 Hz, 1H), 8.04 (dd, J=9.6, 2.5 Hz, 1H), 7.49 (s, 2H), 7.26 (d, J=9.5 Hz, 1H), 4.22 (p, J=6.3 Hz, 1H), 4.12 (dd, J=12.0, 6.5 Hz, 1H), 3.96 (dt, J=10.9, 7.5 Hz, 1H), 3.86 (m, 2H), 2.78 (p, J=7.2 Hz, 1H), 2.65 (td, J=15.3, 14.8, 6.8 Hz, 1H), 2.40 (td, J=13.3, 5.3 Hz, 1H), 1.20 (m, 4H); ESI MS m/z 534 [C28H25Cl2N5O2+H]+; HPLC 99.6% (AUC), tR=10.29 min.
