Reaction Steps
200 ml of dichloro methane (DCM) was added to (L)-tyrosine methyl ester HCl salt (23.16 g, 0.1 mol), and 28 ml of triethyl amine (TEA, 0.2 mol) was added thereto, thereby dissolving HCl salt. The reactor was temperature-lowered to 0° C. by using an ice bath, and 15.46 g of phenylacetyl chloride (0.1 mol) was slowly added, following by stirring for 3˜4 hours. 200 ml of water was added to the reacted material, followed by extraction with 400 ml of ethyl acetate. Drying over sodium sulfate followed by filtering was carried out. The solvent was removed from the filtrate by rotary evaporation, followed by solidification with hexane and ethyl acetate, thereby obtaining a white solid (27.7 g, 88.1% yield).
