Trifluoroacetic anhydride {TFAA) in ether quickly (= 5-10 min) converted tryptophau to the crystalline 2-trifluoromethyl-5(4@-oxazolone (2) without racemization. Dissolution of optically active 2 in acetonitrile gave racemic 2, whereas treatment with hot aqueous dioxane gave the isomeric oxazolone (
