Methyl [[(methoxycarbonyl)amino](methylthio)methylene]carbamate → HCID 178502035, compound

Participants

Reaction Steps

To a solution of 4-(cyclopropylmethyl-amino)-benzenesulfonic acid 3,4-diamino-phenyl ester (648 mg) in acetic acid (4.5 ml) and methanol (40 ml) at 80° C. was added 1,3-bis(methoxycarbonyl)-2-methyl-2-thiopseudourea (580 mg). The reaction mixture was refluxed for 4 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-(cyclopropylmethyl-amino)-benzene sulfonic acid 2-methoxycarbonylamino-1H-benzoimidazol-5-yl ester (378 mg) as a beige solid. Mass spectrum: 417 [M+H]+; retention time=13.16 minutes.
