L-Phenylalanine methyl ester hydrochloride, may be developed in the preparation of aspartame, which is a low-calorie oil. Xia, S. Mixtures of writing acids, including racemic mixtures, may also be able. Chen, S. New Crete. Mixtures of amino acids, including racemic mixtures, may also be used. Accordingly, the present invention is a method comprising reacting amino acid, alcohol, and halocarbonyl compound represented by the formula: STR2 in the presence of an excess of the alcohol with respect to the amino acid, and under substantially anhydrous conditions, to produce ester hydrohalide of the amino acid and the alcohol, wherein X1 and X2 are each independently fluoro, chloro, bromo, trichloromethoxy, or tribromomethoxy. The glycine-, histidine-, and methionine methyl esters were purchased from Fluka. Only one alcohol or a mixture of different alcohols may be employed as desired. EXAMPLE A 1-liter, 4-necked flask equipped with a mechanical agitator, a thermometer, a gas-inlet tube, a vertical condenser cooled by a mixture of solid carbon dioxide and isopropanol, and a gas bubble tube mounted on the outlet of the condenser was charged with
