Participants

Reaction Steps

A mixture of 11.45 parts of 4-phenylcarbamoyloxy-2,2,6,6-tetramethylpiperidine and 60 parts of styrene ⟦ocide⟧ oxide in 60 parts of n-hexanol was heated under reflux conditions for 18 hours. The n-hexanol solvent and unreacted styrene oxide were removed by distillation under reduced pressure to yield a pale yellow crystalline solid. Purification by trituration with hot petroleum ether (b.p. 60°-80° C.) yielded 4-phenylcarbamoyloxy-1-[2'-hydroxy-2-'phenylethyl]-2,2,6,6-tetramethylpiperidine having a melting point of 186°-7° C. with the following elemental analysis by weight:
