Abstract

% Tnfluorometh3. l-Dzs~ e (I) was prepared in 17% yield by the reaction of 2-tdluommethyl4- hydmxy benxenedt aaonium chloride with acrylic acid (Meenvein reaction), followed by ammonolysis. Attempts to prepare I via the &tone route failed. BT~ uoromethyl-nL-tyrosine (11) could not be prepared by either of these pathways, dthough3-tritiuoromethyl-4methoxy- ~~-pheny&nhe waa obtained in impure form by the Meemein route. The critical factor in ...
