It has been found that practical rates of formation of 2,6-difluoropyridine from 2,6-dichloropyridine and KF can be attained without resort to catalysts, high temperatures or large excesses of KF, if:

Process for making 2,6-difluoro pyridine

A process for the preparation of d,1-lysine wherein 2-cyanopyridine is hydrolyzed to picolinamide, the picolinamide is hydrogenated to pipecolamide, the pipecolamide is converted to 1-acetyl-2-cyanopiperidine, the 1-acetyl-2-cyanopiperidine is then converted to a compound which is hydrolyzed to d,1-lysine.
