Participants

Reaction Steps

Trifluoroacetic acid (50 mL of a 10% solution in dichloromethane) was added to tert-butyl 6-amino-3-benzyloxy-11,12-dihydro-8H-[1,4]diazepino[1′,2′:1,2]imidazo[4,5-c]quinoline-9(10H)-carboxylate (2.07 g, 4.50 mmol), and the reaction was stirred at ambient temperature overnight. The solvent was removed under reduced pressure, and the residue was recrystallized from methanol to provide 2.2 g of 3-benzyloxy-9,10,11,12-tetrahydro-8H-[1,4]diazepino[1′,2′:1,2]imidazo[4,5-c]quinolin-6-amine trifluoroacetate.
