Reaction Steps

10-bromo-9-fluoro-3-iodo-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxamide was reacted with (2-tert-butoxycarbonyl-5-methyl-pyrazol-3-yl)boronic acid similarly to as described in Example 4 to produce crude 10-bromo-9-fluoro-3-(3-methyl-1H-pyrazol-5-yl)-5,6dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxamide. 10-bromo-9-fluoro-3-(3-methyl-1H-pyrazol-5-yl)-5,6dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxamide was reacted with (2R)-2-(5-methyl-1,2,4-oxadiazol-3-yl)but-3-yn-2-ol via General Procedure E to afford 5.8 mg (6.6%) 9-fluoro-10-[(3R)-3-hydroxy-3-(5-methyl-1,2,4-oxadiazol-3-yl)but-1-ynyl]-3-(3-methyl-1H-pyrazol-5-yl)-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2-carboxamide following reverse phase purification. M+1=478.
