To a solution of 1,1-bis(methylthio)-2-nitroethylene (1.4 g, 8.33 mmol) in MeOH (75 mL) was added N-(3-Aminophenyl)-3-[(quinolin-4-ylmethyl)amino]thiophene-2-carboxamide (2.1 g, 8.33 mmol) and the mixture was stirred at 85° C. overnight. The reaction mixture was cooled to rt and the yellow precipitate formed was filtered, washed with MeOH, and dried under vacuum to give N-(3-{[1-(methylthio)-2-nitrovinyl]amino}phenyl)-3-[(quinolin-4-ylmethyl)amino]thiophene-2-carboxamide as yellow solid.
