Abstract
A process for preparing nicotinamide, wherein, in the first stage, 2-methyl-1,5-diaminopentane is catalytically converted into 3-picoline, then the 3-picoline is converted via an ammonoxidation into 3-cyanopyridine and, finally, the 3-cyanopyridine is converted microbiologically into the nicotinamide.
