Reaction Steps

Methyl 10-bromo-3-((1,3-dimethyl-1H-pyrazol-4-yl)(hydroxy)methyl)-9-fluoro-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxylate was prepared similarly according to the procedure in Example 9. methyl 10-bromo-9-fluoro-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2-carboxylate was reacted with 1,3-dimethyl-1 h-pyrazole-4-carbaldehyde to afford the crude title compound which was carried forward without further purification.
