实验过程

0.114 g of 3-cyano-L-alanine was dissolved in 5 ml of 1N sodium hydroxide solution and treated with 0.285 g of 2-naphthoyl chloride at 0° C. After acidification with 2M hydrochloric acid and flash chromatography on silica gel using 25% methanol in dichloromethane for the elution there was obtained 0.049 g of 3-cyano-N-(2-naphthoyl)-L-alanine of melting point 95°-100° C.
