Methyl 10-bromo-9-fluoro-3-((1-methyl-1H-pyrazol-5-yl)methyl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxylate was prepared similarly to methyl 10-bromo-9-fluoro-3-((1-methyl-1H-pyrazol-5-yl)methyl)-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxylate. Methyl 10-bromo-9-fluoro-3-(hydroxy(1-methyl-1H-pyrazol-5-yl)methyl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxylate was reacted with methanesulfonyl chloride followed by palladium on carbon and hydrogen to afford 105 mg (85% crude yield) of the titled crude product which was carried forward without further purification.
