1-Methylthio-1-[2-((3-methoxy-2-pyridyl)methylthio)ethylamino]-2-nitroethylene (1.4 g) was stirred with a solution of methylamine in ethanol (25 ml, 33% solution) and dissolved within a minute. After a further 3 minutes a crystalline product separated and recrystallisation from ethanol/ether yielded the title product (1.1 g), m.p. 145.5° - 147°.
