Reaction Steps

Following general procedure D, tert-butyl 1-(5-(6-bromo-3-(cyclopropanecarbonyl)quinolin-4-ylamino)pyrimidin-2-yl)piperidin-3-ylcarbamate (150 mg, 0.26 mmol) was reacted with 2-chloro-6-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (111 mg, 0.39 mmol) to obtain the protected intermediate which was subjected to general procedure A-2 to afford the desired product (16 mg, 11% over 2 steps) as an orange-yellow solid: 1H NMR (500 MHz, MeOD+TFA-d) δ 9.35 (br s, 1H), 8.45 (s, 2H), 8.29 (dd, J=8.8, 1.9 Hz, 1H), 8.26-8.15 (br s, 1H), 8.03 (d, J=8.8 Hz, 1H), 7.07 (br s, 1H), 6.96 (br s, 1H), 4.76 (d, J=12.9 Hz, 1H), 4.45 (br s, 1H), 3.37-3.31 (m, 1H), 2.82 (br s, 1H), 2.23-2.16 (m, 1H), 1.96-1.85 (m, 1H), 1.78-1.68 (m, 1H), 1.68-1.56 (m, 1H), 1.22-1.16 (m, 4H); ESI MS m/z 545 [C29H29ClN6O3+H]+; HPLC 98.5% (AUC), tR=10.69 min.
