Reaction Steps

Following general procedure D, tert-butyl 1-(5-(3-acetyl-6-bromoquinolin-4-ylamino) pyridin-2-yl)pyrrolidin-3-ylcarbamate (80 mg, 0.15 mmol) was reacted with 2-chloro-6-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (65 mg, 0.23 mmol) to obtain the protected intermediate which was subjected to general procedure A-2 to afford the desired product (11 mg, 15% over two steps) as a yellow-brown: 1H NMR (500 MHz, CD3OD+TFA-d) δ 9.28 (s, 1H), 8.31-8.25 (m, 2H), 8.06-7.99 (m, 2H), 7.83 (dd, J=9.2, 2.7 Hz, 1H), 7.04 (d, J=2.2 Hz, 1H), 7.98 (d, J=9.2 Hz, 1H), 6.71 (d, J=2.2 Hz, 1H), 4.16-4.07 (m, 1H), 4.07-3.96 (m, 2H), 3.91 (s, 3H), 3.88-3.79 (m, 1H), 3.79-3.69 (m, 211), 2.80 (s, 3H), 2.63-2.53 (m, 1H), 2.34-2.23 (m, 1H); ESI MS m/z 504 [C27H26ClN5O3+H]+; HPLC 95.4% (AUC), tR=9.37 min.
