Procedure

Concentrated hydrochloric acid (10 mL) was added to a suspension of tert-butyl 4-[8-(chloromethyl)-5,6-dimethyl-7H-imidazo[4,5-c]tetraazolo[1,5-a]pyridin-7-yl]butylcarbamate (1.00 g, 2.30 mmol) in methanol (23 mL). The reaction mixture was stirred at room temperature for 2 hours, then was concentrated under reduced pressure to yield a residue. The residue was concentrated twice from toluene to remove residual water, then was triturated with methanol. A solid was isolated by filtration and was dried under vacuum to provide 0.68 g of 4-[8-(chloromethyl)-5,6-dimethyl-7H-imidazo[4,5-c]tetraazolo[1,5-a]pyridin-7-yl]butan-1-amine hydrochloride.
