Triethylamine (8.39 ml) was added to a suspension of DL-N-acetyl-2-cyclohexylglycine (10.00 g) obtained from α-aminophenylacetic acid according to a known method [Collect. Czeck. Chem. Commun., 31: 4563 (1996)] in ethyl acetate (50 ml). Ethyl chlorocarbonate (5.28 ml) was dropwise added to the mixture under ice-cooling. The mixture was stirred under ice-cooling for one hour, added with ethyl acetate (150 ml), and washed successively with water and saturated brine. The ethyl acetate solution was concentrated under reduced pressure to give 9.86 g of the title compound as an oil.
