Butylamine → n-Butyl-2,2,6,6-tetramethyl-4-piperidinamine

참여 물질

반응 단계

155 g of 2,2,6,6-tetramethyl-4-piperidone and 80.0 g of butylamine were dissolved in 300 ml of methanol, and then 2.0 g of platinum oxide were added to the resulting solution, after which the solution was shaken under a pressure of 3 atmospheres of hydrogen in a medium-pressure hydrogenation apparatus at room temperature for 5 hours. At the end of this time, the platinum catalyst was filtered off, and the solvent was removed from the filtrate by distillation under reduced pressure, after which the residue was further purified by distillation under reduced pressure, to yield 201.5 g of the title compound as an oil boiling at 100° to 101° C./5 mmHg (667 Pa).
