Reaction Steps
An intimate mixture of 2-amino-5-nitropyridine (19.0 g) and 1,1-bis(phenylsulphonyl)-2-ethoxyethene (30 g) was heated at 180°-190° C. for 1 hour. After cooling, the solid cake was pulverised and recrystallised from a mixture of methyl ethyl ketone and methanol, to give 1,1-bis(phenylsulphonyl)-2-(5-nitropyrid-2-ylamino)ethene (28 g) m.p. 229°-231° C.
