Reaction Steps

To a solution of N-(tert-butoxycarbonyl)-N′-ethyl-N″-(1-(4-methylpyridin-2-yl)pyrrolidin-3-yl)guanidine (200 mg) in ethanol (2 ml) was added a solution of hydrogen chloride in 1,4-dioxane (4N, 3 ml), and the mixture was stirred at ambient temperature for 6 hours. The solvent was evaporated under reduced pressure. To the residue was added 10% ethanol in ethyl acetate (50 ml), and the resultant precipitate was collected by filtration and dried under reduced pressure to give N-ethyl-N′-(1-(4-methylpyridin-2-yl)pyrrolidin-3-yl)guanidine dihydrochloride (120 mg).
