실험 절차

0.25 g (1.39 mmol) of 2-ethoxy-6-hydroxybenzenecarboximidamide is stirred without solvent with 0.65 g (3.28 mmol) of 1,1′-sulphonyldiimidazole at 130° C. for 18 hours. Cooling is followed by stirring the mixture with water and removing with dichloromethane. The organic phase is dried over magnesium sulphate and concentrated under reduced pressure. This gives 0.2 g of a pale yellow, crystalline material.
