Participants

Reaction Steps

10-Bromo-2-carbamoyl-9-fluoro-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-3-carboxylic acid (85 mg) was reacted with aminoacetonitrile hydrochloride similar to as described in Example 2 to produce 75 mg crude 10-bromo-N3-(cyanomethyl)-9-fluoro-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2,3-dicarboxamide which was then reacted with (2R)-2-(5-methylisoxazol-3-yl)but-3-yn-2-ol similar to as described in Procedure E to afford 26.1 mg of N3-(cyanomethyl)-9-fluoro-10-[(3R)-3-hydroxy-3-(5-methylisoxazol-3-yl)but-1-ynyl]-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2,3-dicarboxamide following reverse phase hplc purification.
