反応手順
5.0 g of m-methylsulfonylbenzonitrile (101°-103° C.), 2.8 g of dicyanodiamide and 2.0 g of caustic potash are refluxed in 20 ml of methyl cellosolve for 3 hours. After cooling, the mixture is diluted with water, and the separated crystals are recrystallized from ethanol. Melting point: 228°-289° C.; yield: 4.8 g.
