Procedure
Intermediate 10A was prepared from 4-bromoisoquinoline and 4-(tert-butoxy carbonylamino)phenylboronic acid by the procedure described for the preparation of Intermediate 1C, and was obtained as an off-white foam (63% yield). MS (ES): m/z=321.2 [M+H]+. HPLC Ret timea: 2.432 min. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.51 (s, 9 H) 7.44 (d, J=8.53 Hz, 2 H) 7.65 (d, J=8.53 Hz, 2 H) 7.68-7.75 (m, 1 H) 7.75-7.82 (m, 1 H) 7.88 (d, J=8.53 Hz, 1 H) 8.20 (d, J=7.78 Hz, 1 H) 8.40 (s, 1 H) 9.31 (s, 1 H) 9.57 (s, 1 H).
