Reaction Steps

To a solution of N,N′-bis(tert-butoxycarbonyl)-N″-(3-(3-aminopyridin-2-yl)phenyl)guanidine (150 mg) in dichloromethane (1.5 ml) was added 4N hydrogen chloride in 1,4-dioxane (3 ml), and the mixture was stirred at room temperature for 26 hours. The solvent was evaporated under reduced pressure. To the residue was added 5% ethanol in ethyl acetate (100 ml), and the precipitate was collected by filtration and dried under reduced pressure to give 3-(3-aminopyridin-2-yl)phenylguanidine dihydrochloride (92 mg).
