실험 절차

3-Bromopyridin-2-amine (30 g, 168 mmol) and ethoxycarbonyl isothiocyanate (24.8 g, 21.3 mL, 185 mmol) were dissolved in dioxane (300 mL) and stirred at room temperature. After 4 hours further ethoxycarbonyl isothiocyanate (1 mL, 8.4 mmol) was added. After 1 hour the solvent was evaporated and the residue dried in high vacuum for 12 hours. The title compound was obtained as a light yellow solid (51.2 g, 100%) and was used crude for the next step.
