Reaction Steps

2-Bromo-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine was reacted with 2-aminopyrimidine-5-boronic acid pinacol ester using standard Suzuki coupling procedure. Purification on silica and triturating with diethyl ether gave 163. 1H NMR (400 MHz, CDCl3), 3.26 (2H, t, J=5.14), 4.37 (2H, t, J=5.18), 5.16 (2H, Broad s), 7.02-7.09 (3H, m), 7.16-7.22 (1H, m), 7.70 (1H, d, J=7.91), 8.56 (2H, s). MS: (ESI+) 396
