Procedure
To a suspension of N-(3-(4-methoxypyridin-2-yl)phenyl)thiourea (104 mg) in N,N-dimethylformamide (2 ml) were added a solution of hydrogen chloride in 1,4-dioxane (4N, 0.2 ml) and iodopropane (0.195 ml), and the mixture was stirred at 50° C. for 2 hours. Ethyl acetate (100 ml) was added to the mixture, and the mixture was cooled. The precipitate was collected by filtration. The precipitate was dissolved in water, and to the solution was added a saturated aqueous sodium hydrogencarbonate solution and extracted with dichloromethane. The organic layer was washed with brine, dried over sodium sulfate and evaporated under reduced pressure. The residue was dissolved in ethyl acetate, and to the solution was added a solution of hydrogen chloride in 1,4-dioxane (4N, 0.5 ml). The precipitate was collected by filtration and dried under reduced pressure to give N-(3-(4-methoxypyridin-2-yl)phenyl)-S-propylisothiourea dihydrochloride (143 mg).
