Procedure
Using 1-hydroxy-4-benzoyloxy-2,2,6,6-tetramethylpiperidine, prepared as described by: Kurumada T. et. al., loc. cit., and diphenylphosphinic chloride in a procedure otherwise similar to that for preparing the compound 101 gives an 84% yield of the compound 116 which is obtained in the form of colourless crystals; melting point: 169–173° C. (dichloromethane/hexane).
