Reaction Steps

3-(3-cyclopropyl-1H-1,2,4-triazol-5-yl)-9-fluoro-10-(3-hydroxy-4-methoxy-3-methyl-but-1-ynyl)-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2-carboxamide was prepared similarly according to General Procedure E with slight modification. 10-bromo-3-(3-cyclopropyl-1H-1,2,4-triazol-5-yl)-9-fluoro-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2-carboxamide was reacted with 1-methoxy-2-methyl-but-3-yn-2-ol in a solution of DMF (1.3 mL/mmol) and diisopropylamine (2.6 mL/mmol) to afford 17 mg of the titled compound (26.3% yield).
