Oxygen → N-Ethylnicotinamide

Participants

Reaction Steps

In a 100 ml three-necked flask were charged 2 g of pyridine-3-aldehyde, 50 g of a 30 weight percent aqueous ethylamine solution and 3 g of the same commercially available palladium catalyst as in Example 1. The reaction was conducted at a reaction temperature of 30° C. for 2 hours by introducing oxygen at a rate of 10 l/hour into the flask from its gas inlet equipped with a filter to give nicotinic acid monoethylamide at a yield of 47%.
