Procedure
A solution of 0.16 g ethyl 2-oxo-4-(tetrahydropyran-2-yl)-1-pyrrolidineacetate is dissolved in 5 ml ethanol containing 16 mg pyridinium p-toluenesulphonate. The mixture is heated 4 h at 35°, the ethanol is evaporated and the residue chromatographed on silica. The title compound is obtained as a colourless oil in 62% yield.
