1,1-Bis(methylthio)-2-nitroethylene → HCID 72727591, compound

Participants

Reaction Steps

A mixture of N-(2-chloro-5-pyridylmethyl)-N-methylethylenediamine (2.0 g), 1-nitro-2,2-bis(methylthio)ethylene (1.7 g) and ethanol (40 ml) was refluxed for 5 hours with stirring. The reaction mixture was concentrated to about half of its volume, and cooled. The precipitated crystals were collected by filtration, washed with a small amount of ethanol, and dried to give the desired N-(2-chloro-5-pyridylmethyl)-N-methyl-N'-(1-methylthio-2-nitrovinyl)ethylenediamine (1.8 g) having a melting point of 93° to 95° C.
