Reaction Steps

10-Bromo-2-carbamoyl-9-fluoro-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-3-carboxylic acid (55 mg) was reacted with 4-aminotetrahydropyran similar to as described in Example 2 to produce crude 10-bromo-9-fluoro-N3-tetrahydropyran-4-yl-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2,3-dicarboxamide which was then reacted with 2-Methyl-3-butyne-ol similar to as described in Procedure E to afford 12.5 mg of 9-fluoro-10-(3-hydroxy-3-methyl-but-1-ynyl)-N3-tetrahydropyran-4-yl-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2,3-dicarboxamide following reverse phase hplc purification.
