Reaction Steps
A 2.25N aqueous solution of lithium hydroxide (4.0 ml, 9.0 mmoles) and 6 ml of tetrahydrofuran were added to 0.492 g (3.0 mmoles) of phenylpyruvic acid. The mixture was gradually heated with ice cooling to react it for 12 hours. After the reaction, 20 ml of 1N hydrochloric acid was added, and the mixture was extracted with ether. The organic layer was dried over magnesium sulfate. The drying reagent was separated by filtration, and the solvent was evaporated under reduced pressure to give a pale white solid. The NMR spectral analysis of this product led to the determination that 2-oxo-3-phenylbutanoic acid formed in a yield of 85 %, and 2-oxo-3-methyl-3-phenylbutanoic acid, in a yield of 4 %.
