Reaction Steps
A solution of 4.66 g (40 mmol) of n-butyl isocyanate in 10 ml of toluene is added over 10 minutes to a suspension of 10.6 g (38.2 mmol) of 1-hydroxy-4-benzoyloxy-2,2,6,6-tetramethylpiperidine in 40 ml of toluene. The reaction mixture is heated at 50° C. for 30 minutes. The reaction mixture is then filtered, and the residue from evaporation of the filtrate is crystallized from hexane to give 4.2 g (29% yield) of a white solid, m.p. 126-27° C.
