Borane THF complex (2.76 mL of a 1 M solution in THF) was added to a solution of 6-amino-12-methyl-8,9,11,12-tetrahydro-10H-[1,4]diazepino[1′,2′:1,2]imidazo[4,5-c]quinolin-10-one (0.389 g, 1.38 mmol) in THF (5 mL), and the mixture was stirred at room temperature overnight and then heated at reflux for six hours. An analysis by LC/MS indicated the reaction was incomplete, and additional borane tetrahydrofuran complex (2.76 mL) was added. The reaction mixture was heated at reflux overnight, allowed to cool, and concentrated under reduced pressure. The residue was treated with chloroform, and a solid was present that was isolated by filtration to provide 12-methyl-9,10,11,12-tetrahydro-8H-[1,4]diazepino[1′,2′:1,2]imidazo[4,5-c]quinolin-6-amine as a yellow solid.
