Procedure
A mixture of 3.0 g (7.68 mmol) of 4-[2-(acetylamino)phenyl]-1,3-dihydro-1-[1-(phenylmethyl)-4-piperidinyl]-2H-imidazol-2-one, 50 ml of 5 N sodium hydroxide solution and 25 ml of ethanol was refluxed for 3 hours. After cooling the organic phase was separated off, dried over sodium sulphate and evaporated down in vacuo. A colourless amorphous substance was obtained in a quantitative yield, Rf=0.53 (eluant: dichloromethane/methanol 9/1 v/v).
