Participants

Conditions

Temperature: 80 °C

Procedure

A solution of 63.0 g (0.25 mole) of N-(2,2,6,6-tetramethylpiperidin-4-yl)-epsilon-caprolactam, prepared in Example 1, in 150 ml of toluene is added to a flask fitted with a reflux condenser, stirrer and thermometer. To this solution is then added a second solution of 28.5 ml (0.30 mole) of dimethyl sulfate in 100 ml of toluene. The mixture is heated for one hour at 80° C. and then 50 ml of concentrated ammonium hydroxide is added.
