Procedure
Following Example 182, 10-bromo-2-(1-isopropyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine 187 was coupled with tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole-1-carboxylate to give 160. MS: 362.3. 1H NMR (400 MHz, DMSO) δ 8.57 (t, J=4.0, 1H), 7.99-7.94 (m, 4H), 7.56 (dt, J=11.2, 5.6, 1H), 7.06 (t, J=8.6, 1H), 5.81 (p, J=6.6, 1H), 4.53 (d, J=9.5, 4H), 1.53 (d, J=6.6, 7H).
