Reaction Steps

3-((3,5-difluorophenyl)(hydroxy)methyl)-9-fluoro-10-(3-hydroxy-3-methylbut-1-yn-1-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxamide was prepared similarly according to General Procedure G with slight modifications. 10-bromo-3-((3,5-difluorophenyl)(hydroxy)methyl)-9-fluoro-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxamide was reacted with 3-methyl-1-butyne-3-ol to afford 25.7 mg of the titled compound (45% yield).
