摘要：
This invention relates to a new composition of matter known as 2-Methyl-4-benzyl-5-oxazolidinone and a method of preparation of the new composition comprising combining ethyl acetate and the azlactone of .alpha.-acetoaminocinnamic acid in the presence of a catalyst such as W-2 Raney nickel. By using the new composition of matter of this invention the synthesis of L-phenylalanine is shortened to fewer reactions and process steps from the current lengthy, multistep means of synthesis.
