Procedure
Methyl 10-bromo-2-carbamoyl-9-fluoro-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-3-carboxylate (2 g) was reacted with 2-Methyl-3-butyne-ol similar to as described in Procedure E to afford 2 g of methyl 2-carbamoyl-9-fluoro-10-(3-hydroxy-3-methyl-but-1-ynyl)-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-3-carboxylate following triteration from water. MS (Q1) 388 (M)+. Methyl 2-carbamoyl-9-fluoro-10-(3-hydroxy-3-methyl-but-1-ynyl)-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-3-carboxylate (1.5 g) was saponified with LiOH in water/THF to afford quantitative yield of 2-carbamoyl-9-fluoro-10-(3-hydroxy-3-methyl-but-1-ynyl)-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-3-carboxylic acid. MS (Q1) 383 (M)+.
