Reaction Steps
In the same flask as in Example 1 were charged 2 g of pyridine-3-aldehyde, 5 g of benzylamine, 40 g of N,N-dimethylformamide and 3 g of a catalyst in which 5 percent by weight of platinum metal together with lead hydroxide with an atomic ratio of Pt to Pb being 1 to 1 had been supported on alumina. The reaction was conducted at a reaction temperature of 25° C. by introducing air into the flask at a rate of 6 l/hour for 2 hours to give nicotinic acid benzylamide at a yield of 23%.
