Reaction Steps

9-Bromo-2-(1H-imidazol-2-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine was alkylated with 4-(2-chloroethyl)morpholine to give 9-bromo-2-[1-(2-morpholinoethyl)-1H-imidazol-2-yl]-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (yield 51%. MS: 444.2) which was coupled under Suzuki palladium coupling conditions of Example 182 with tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole-1-carboxylate to give 209. Yield 24%.
