Reaction Steps

Excess HCl gas was added with stirring to a suspension of L-phenylalanine or L-tyrosine in excess isopropanol. The mixture was heated to reflux for 16 h, and then the volatiles were evaporated under vacuum to give L-phenylalanine isopropyl ester hydrochloride or L-tyrosine isopropyl ester hydrochloride of sufficient purity for immediate use.
