The intermediate 3-chloro-4-amino-D-phenylalanine (V) was synthesized from 4-amino-D-phenylalanine (I). Esterification with a methanolic solution of HCl, prepared from MeOH and AcCl, gave methyl ester (II), and subsequent acylation by means of Ac2O and pyridine afforded diacetamide (III). Halogenation of (III) using N-chlorosuccinimide produced chloride (IV). Basic hydrolysis of (IV) cleaved the methyl ester and one of the acetyl groups, and subsequent treatment with strong acid removed the remaining acetyl group yielding (V).
