実験手順
2-Chloro-3-cyano-5,4'-bipyridine-1'-oxide and 3 g N,N-dimethylammonium-N,N-dimethyl carbamate is heated in 50 ml dimethylformamide for 2 hours on the boiling water bath and then allowed to cool. The crystalline precipitate, formed on standing overnight in the refrigerator, is filtered off with suction, crystallized from dimethylformamide and dried at 110° C. Yield: 2.9 g (93.2% of the theoretical yield), with a melting point of 282° C.-284° C.
