Versuchsvorschrift
Concretely, 4-nitro-L-phenylalanine and 2,6-dichlorobenzoylchloride are condensed in a mixed solvent of a sodium hydroxide aqueous solution and acetone with keeping the reaction temperature at 5 to 15° C., and then crystallization is conducted to obtain a corresponding condensed substance, Nα-(2,6-dichlorobenzoyl)-4-nitro-L-phenylalanine almost quantitatively.
