실험 절차

Into a one liter reactor fitted with warming, cooling and stirring means were poured 108.5 g (0.39 mol) of bis (S-methylisothiourea) sulphate, 150 ml of water and 94 ml (or 68 g, i.e. 1.15 mol) of isopropylamine. The mixture was refluxed for two hours and then evaporated to dryness. The residue was taken up in ethanol from which there was obtained, after filtration, washing and drying, 96 g (yield 82%) of product.
