Reaction Steps

Following general procedure D, tert-butyl 1-(5-(6-bromo-3-(cyclopropanecarbonyl)quinoline-4-ylamino)pyrimidin-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 (35 mg, 36% over 2 steps) as a yellow-orange solid: 1H NMR (500 MHz, CD3OD+TFA-d) δ 9.34 (s, 1H), 8.47 (s, 2H), 8.26 (m, 2H), 8.04 (d, J=8.8 Hz, 1H), 7.41 (s, 2H), 4.07 (m, 2H), 3.91 (m, 1H), 3.81 (m, 2H), 2.81 (s, 1H), 2.52 (m, 1H), 2.23 (tt, J=13.0, 5.7 Hz, 1H), 1.20 (s, 4H); ESI MS m/z 535 [C27H24Cl2N6O2+H]+; HPLC 100.0% (AUC), tR=10.30 min.
