Procedure
To a solution of N,N′-bis(tert-butoxycarbonyl)-N″-(3-(3-tert-butyldimethylsilyloxymethylpyridin-2-yl)phenyl)guanidine (300 mg) in dichloromethane (3 ml) was added a solution of hydrogen chloride in 1,4-dioxane (4N, 6 ml), and the mixture was stirred at room temperature for 24 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-hydroxymethylpyridin-2-yl)-phenylguanidine dihydrochloride (1I40 mg).
