Hydrochloric Acid → 1-(2-aminoethyl)-2-(2-methoxyethyl)-1H-imidazo[4,5-c][1,5]naphthyridine-4-amine hydrochloride

Participants

Reaction Steps

A solution of hydrochloric acid in dioxane (58 mL of 4 M) was added to a solution of tert-butyl N-{2-[4-amino-2-(2-methoxyethyl)-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl]ethyl}carbamate (3 g) in a small amount of dichloromethane/methanol. The reaction mixture was stirred overnight at ambient temperature and then concentrated under reduced pressure to provide 3.7 g of crude 1-(2-aminoethyl)-2-(2-methoxyethyl)-1H-imidazo[4,5-c][1,5]naphthyridine-4-amine hydrochloride.
