Participants

Reaction Steps

Hydrogen chloride (25 mL of a 4 N solution in 1,4-dioxane) was added to a solution of tert-butyl 3-benzyloxy-11,12-dihydro-8H-[1,4]diazepino[1′,2′:1,2]imidazo[4,5-c]quinoline-9(10H)-carboxylate in a 1:1 mixture of dichloromethane and diethyl ether (50 mL). The reaction was stirred overnight at ambient temperature; a precipitate formed. The precipitate was harvested via filtration and dried under reduce pressure to provide 9.66 g of 3-benzyloxy-9,10,11,12-tetrahydro-8H-[1,4]diazepino[1′,2′:1,2]imidazo[4,5-c]quinoline.
