실험 절차

Reaction of o-nitrobenzaldehyde (41.7 g., 0.276 mole) with N,N-diethyl-6-methylnicotinamide (53.1 g., 0.276 mole) in the presence of acetic anhydride (56.3 g., 0.552 mole) according to the method of L. Horwitz, J. Org. Chem., 21, 1039 (1956) provides 67.4 g. (75%) of N,N-diethyl-6-(o-nitrostyryl)nicotinamide. Crystallization from acetonitrile affords the analytically pure nicotinamide having a melting point of 145°-147°C. (corr.).
