Reaction Steps

Approximately 1 equivalent of homoserine, 0.01 equivalent of sulfuric acid may be combined with water in a reactor. The reactor may be sealed and 1.1 equivalent of anhydrous HCl (gas) may be may be added to the reactor. The reaction mixture may be heated to about 70° C. and maintained at about 80 psi for about 24 hours. The reaction mixture may be cooled and about 10 equivalents of methanol may be added, such that the product precipitates. The product (i.e., 4-chloro-2-aminobutanoic acid hydrochloride) may be isolated by filtration.
