Procedure

6 Parts of 4(4'-hydroxyphenyl)-2,2,6,6-tetramethylpiperidine were treated with excess acetic acid in a similar manner to Example 9. The residue obtained after evaporation was crystallised from a chloroform-methanol-petroleum mixture to afford 5.7 parts of the desired product melting at 220°-240° and having the following elemental analysis.
