Versuchsvorschrift
1.00 g of methyl (E)-4-{4-((1-methylthio-2-nitroethen-1-yl)amino)phenyl}-3-butenoate was suspended in 5 ml of methanol, followed by the addition of 1.25 ml of a 40% solution of methylamine in methanol. The obtained mixture was stirred at a room temperature for 4 hours and distilled to remove the solvent. The residue was purified by silica gel column chromatography [solvent: dichloromethane/methanol (30:1)] to obtain 0.5 g of the title compound as a pale yellow solid (yield: 54%).
