실험 절차

A mixture of 3-phenyl-1H-1,2,4-triazole (1.46 g, 9.05 mmol), 3-chloropropionic acid (1.08 g, 9.96 mmol) and sodium hydroxide (2M, 9.05 mL, 18.1 mmol) in water (3 mL) was heated to 115° C. and stirred for 66 h. Another 0.5 equivalents of each 3-chloropropanoic acid and sodium hydroxide were added (pH increase to 11) and stirring was continued for another 24 h. Hydrochloric acid (2M, 10 mL) was added, the suspension was filtered and extracted with dichloromethane. The product was obtained after purification by supercritical fluid chromatography as light brown solid (236 mg, 1.09 mmol, 12.0%). MS: M=218.1 (M+H)+
