Reaction Steps

A mixture of 12.8 grams (50.0 mmol) of 1-cyclohexyloxy-4-hydroxy-2,2,6,6-tetramethylpiperidine, 5.0 grams (50.0 mmol) of succinic anhydride and 15 ml of toluene is heated at reflux for five minutes. Solvent is evaporated and the residue is dissolved in hexane. Water is added and the resulting precipitate is washed with hexane to afford 16.1 grams (90% yield) of the title compound as the monohydrate as a white solid melting at 56°-60° C.
