To a solution of 26 mmol sodium hydroxide in 7 ml water 8.7 mmol of glycine were added. The mixture was cooled in an ice-bath and a solution of 8.7 mmol 3-(4-chloro-phenyl)-propionyl chloride (CA [52085-96-8]) in 10 ml dioxane was slowly added over a period of 20 minutes. After stirring overnight at room temperature, the mixture was extracted with diethyl ether. The aqueous phase was acidified by addition of diluted hydrochloric acid and filtered. Trituration of the solid in diethyl ether yielded the title compound as a colorless solid. Yield=42%.
