10-bromo-9-fluoro-3-iodo-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxamide was reacted with 2-methyl-1-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrazol-1-yl]propan-2-ol similarly to as described in the synthesis of 9-fluoro-10-(3-hydroxy-3-methyl-but-1-ynyl)-3-[(4-methylpiperazin-1-yl)methyl]-5,6,7,12-tetrahydro-5,7-methanobenzo[e]imidazo[1,2-a]azepine-2-carboxamide to produce crude 10-bromo-9-fluoro-3-(1-(2-hydroxy-2-methylpropyl)-1H-pyrazol-4-yl)-5,6-dihydrobenzo[f]imidazo [1,2-d][1,4]oxazepine-2-carboxamide. This intermediate was reacted with (2R)-2-(5-methylisoxazol-3-yl)but-3-yn-2-ol via General Procedure E to afford 25 mg (27%) of 9-fluoro-10-[(3R)-3-hydroxy-3-(5-methylisoxazol-3-yl)but-1-ynyl]-3-[1-(2-hydroxy-2-methyl-propyl)pyrazol-4-yl]-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2-carboxamide.
