Procedure

50 g of 1-cyano-1-methylethylphenyl carbonate and 25 g of 4-hydroxypiperidine were heated at 130° C. After completion of the reaction, the resulting product was purified by silica gel column chromatography (elution solvent: hexane:ethyl acetate=1:1-1:2-0:1), thereby obtaining 50.5 g of the intended compound.
