Procedure
A solution of 26 g of potassium bicarbonate in 55 ml of water was added under storing stirring to a solution of 2-(4-methoxy-phenoxymethyl)thiazolidine (54,5 g) in 550 ml of ethyl acetate cooled at 0°-5° C. The mixture was added with a solution of α-chloro-acetylchloride (19,2 ml) in ethyl acetate (50 ml) for 1 hour, under strong stirring and external cooling. Stirring was continued for 2 more hours, then the phases were separated. After washing of the organic phase with water, 5% aqueous NaHCO3 and water, and drying over Na2SO4, the mixture was evaporated to dryness to give 54,5 g of 2-(4-methoxy-phenoxymethyl)-3-α-chloroacetyl-thiazolidine, m.p. 51°-53° C. (from isopropyl alcohol).
