Procedure

To a solution of N,N-bis(tert-butoxycarbonyl)-N″-(3-(3-carboxypyridin-2-yl)phenyl)guanidine (220 mg) in dichloromethane (2 ml) was added a solution of hydrogen chloride in 1,4-dioxane (4N, 4 ml), and the mixture was stirred at room temperature for 16 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-carboxypyridin-2-yl)phenylguanidine dihydrochloride (144 mg).
