Procedure

23.0 g of N-(1'-methoxycarbonyl-ethyl)-N-methoxyacetyl-2,6-dimethyl-3-acetoxymethylaniline, 9.2 g of 30% sodium hydroxide solution and 100 ml of acetone were stirred for 3 hours at room temperature; 20 ml of water were then added, and the reaction mixture was extracted twice with 50 ml of diethyl ether each time. The combined ether extracts were dried over sodium sulfate, and the solvent was evaporated off. The oily crude product was chromatographed through a silica gel column by means of ether/chloroform (1:1) to thus obtain the product in the form of colourless oil: nD14 =1.5352.
