실험 절차

To a solution of 4-benzyloxy-benzenesulfonic acid 3,4-diamino-phenyl ester (134 mg) in acetic acid (0.83 ml) and methanol (2.5 ml) at 80° C. was added 1,3-bis(methoxycarbonyl)-2-methyl-2-thiopseudourea (89 mg). The reaction mixture was refluxed for 2 hours then allowed to cool to ambient temperature and stirred at this temperature for 14 hours. The resultant precipitate was filtered, washed with diethyl ether and dried under vacuum to afford 4-benzyloxy-benzenesulfonic acid 2-methoxycarbonylamino-1H-benzoimidazol-5-yl ester as a beige solid. Mass spectrum: 454 [M+H]+; retention time=11.46 minutes.
