Procedure

A solution in methanol (5 ml) of ethylamine (225 mg) was added dropwise over 2 minutes to a stirred solution in methanol (30 ml) at 32° of 1-methylsulphinyl-1-methylthio-2-nitroethylene (906 mg). Evaporation of the reaction mixture gave an oil which was crystallised from isopropanol to give the title product (230 mg) m.p. 66°-67.5°.
