Reaction Steps

To a solution of N,N′-bis(tert-butoxycarbonyl)-N″-(2-methyl-5-(4-methylpyridin-2-yl)phenyl)guanidine (200 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 were added ethanol (2 ml) and ethyl acetate (10 ml), and the precipitate was collected by filtration and dried under reduced pressure to give (2-methyl-5-(4-methylpyridin-2-yl)phenyl)guanidine dihydrochloride (127 mg).
