Participants

Reaction Steps

10-bromo-2-carbamoyl-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-3-carboxylic acid was reacted with tetrahydro-pyran-4-ylamine hydrochloride similarly to as described in example 2 with non-critical modifications to afford 117 mg (63%) 10-bromo-N3-tetrahydropyran-4-yl-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2,3-dicarboxamide. 10-bromo-N3-tetrahydropyran-4-yl-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2,3-dicarboxamide was reacted with (3R)-3-ethynyl-3-hydroxy-1-methyl-pyrrolidin-2-one similarly to as described in General Procedure F with non-critical modifications to afford 14 mg (11%) of 10-[2-[(3R)-3-hydroxy-1-methyl-2-oxo-pyrrolidin-3-yl]ethynyl]-N3-tetrahydropyran-4-yl-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-2,3-dicarboxamide.
