1,1-Bis(methylthio)-2-nitroethylene → 2-(Nitromethylene)imidazolidine

Participants

Reaction Steps

A mixture of N-(3-pyridylmethyl)ethylenediamine (15.1 g), 1-nitro-2,2-bis(methylthio)ethylene (18.2 g) and benzene (150 ml) was refluxed for 4 hours with stirring. The qenerated gas was collected by an alkali trap. The reaction mixture was cooled to room temperature, and filtered to collect crystals. Recrystallization from methanol gave 1-(3-pyridylmethyl)-2-(nitromethylene imidazolidine (17 g) of the following formula as pale yellow crystals. mp. 169°-171° C. ##STR15##
