Procedure

The 1-dimethylamino-1-methylthio-2-nitroethylene (1.0 g) prepared in (1) and 1.0 g of 6-chloro-3-pyridylmethylamine were refluxed in 30 ml of EtOH for 2 hours. The EtOH was then distilled off and the residue was subjected to silica gel column chromatography using CHCl3 -MeOH (10:1) as an eluent. The crystals obtained were recrystallized from EtOH to recover 0.82 g of the title compound as pale yellow crystals.
