Procedure
Using 1-hydroxy-4-benzoyloxy-2,2,6,6-tetramethylpiperidine (prepared as described by: Kurumada T. et. al., loc. cit.) and pivaloyl chloride in a procedure otherwise similar to the preparation of the compound 101 gives a 70% yield of the compound 107 which is obtained in the form of colourless crystals; melting point: 107-110° C. (hexane).
