실험 절차

A mixture of (6-methoxy-1H-benzoimidazol-2-ylsulfanyl)-acetic acid ethyl ester (14.70 g, 55.26 mmol), hexamethylenetetramine (15.47 g, 100.53 mmol) and trifluoroacetic acid (61 mL) was stirred under argon atmosphere at 120° C. for 1 h. The solution was cooled to room temperature and water (950 mL) was added. This aqueous mixture was extracted with EtOAc (3×200 mL). The combined organic layers were dried over Na2SO4 and evaporated. The title compound (1.432 g, 4.87 mmol, 9%) was obtained by column chromatography in 2 consecutive steps followed by trituration with diethyl ether.
