실험 절차

From a solution of the sodium salt of 4-(dimethylaminosulfonyl)benzoylacetaldehyde in 2 l. of water (prepared from 36.1 g. of sodium methoxide in 500 ml. of tetrahydrofuran, 49.5 g. of ethyl formate, and a solution of 137.8 g. of 4-acetyl-N,N-dimethylbenzenesulfonamide in 1.4 l. of tetrahydrofuran) and 76.6 g. of cyanoacetamide, there is obtained 6-[4-dimethylaminosulfonyl)phenyl]-1,2-dihydro-2-oxonicotinonitrile; m.p. 263°-267° C. (dec.) after crystallization from aqueous dimethylformamide.
