Yield:-

Reaction Conditions:

with ammonia;hydrogen;Ni-5584 in ethanol at 180; under 135014 Torr; for 6 h;Product distribution / selectivity;

Steps:

4
Example 4 starting from 2-cyanopyridine; A mixture of 25 g of Ni-5584 and 127.5 g of liquid ammonia was treated with 100 bar of hydrogen and heated to 180° C. After increasing the hydrogen pressure to 180 bar, 250 g of 2-cyanopyridine in 125 g of ethanol was added over the course of 6 hours. When the hydrogen absorption was complete, the system is cooled, expanded, and aerated with nitrogen, and the catalyst was filtered off. The resulting crude product had a 52% content of 2-aminomethylpiperidine.
