Procedure

A Parr shaker bottle containing 20.0 g (0.117 mol) 1-oxyl-2,2,6,6-tetramethylpiperidin-4-one, 6.0 g (0.058 mol) diethylenetriamine, 0.5 g 8% Pt/2% Pd on Carbon and 120 mL methanol is pressurized with hydrogen and shaken for 2 hours. The catalyst is removed by filtration and the solution is concentrated to 40 mL. The product is precipitates as a white solid with the addition of 200 mL of ethyl ether: mp 118–124° C.
