실험 절차
A solution of p-chlorophenylglycine (46.9 g, 0.25 mole) in a mixture of acetonitrile, xylenes and dimethyl formamide (74.8 w/w%, 24.9 w/w% and 0.3 w/w%, respectively) is treated sequentially with PCl3 (21.3 g, 0.155 mole) and trifluoroacetyl chloride (34.8 g, 0.26 mole), held at 40° C. for 0.5 hour, heated at 60° -65° C. for 8 hours and allowed to cool to room temperature. The title product is obtained in quantitative yield by HPLC analysis.
