Procedure
According to the above procedure, by reacting 0.02 mol of 3-amino-N-[2-(5-dimethylaminomethylfuran-2-ylmethylthio)ethyl]benzamide and 0.02 mol of 1,1-bis-methylthio-2-nitroethene in 50 ml of ethanol, the 3-[N-(1-methylthio-2-nitroethenyl)amino]-N-[2-(5-dimethylaminomethylfuran-2-ylmethylthio)ethyl]benzamide is obtained in 65% yield, said compound being then dissolved in ethanol and treated with a 33% solution of methylamine in ethanol to give the 3-[N-(1-methylamino-2-nitroethenyl)amino]-N-[2-(5-dimethylaminomethylfuran-2-ylmethylthio)ethyl]benzamide as a practically pure oil. The product thus obtained is transformed into its oxalate in 95% ethanol. After crystallization from 200 ml of ethanol, the pure oxalate is obtained in 43% yield; m.p. 175°-177° C.
