실험 절차

2-Bromo-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine from Example 73 was reacted with indazole 4-boronic acid pinacol ester using standard Suzuki coupling procedure. Purification on prep HPLC and triturating with hexanes gave 140. 1H NMR (400 MHz, CDCl3): 3.34 (2H, t), 4.42 (2H, t), 7.07-7.11 (2H, m), 7.18-7.22 (1H, m), 7.35 (1H, s), 7.42-7.49 (3H, m), 7.79 (1H, dd), 8.50 (1H, s). MS: (ESI+) 319
