Procedure
N-(Indan-2-yl)glycine benzyl ester hydrochloride (6 g) is added to a mixture of 300 ml of ethyl acetate and 200 ml of 5% aqueous potassium carbonate, followed by vigorous stirring. To the resulting solution is added dropwise 6 ml of chloroacetyl chloride over 30 minutes with ice cooling. Thereafter, stirring is continued for an hour. The ethyl acetate layer is then separated, washed with water and dried over anhydrous magnesium sulfate, and the solvent is distilled off under reduced pressure. Addition of ether to the residue gives 6 g of N-chloroacetyl-N-(indan-2-yl)glycine benzyl ester as colorless scales melting at 99.5°-100.5° C.
