実験手順

6.4 g of gamma-aminobutyric acid and 4.5 g of sodium hydroxide were dissolved in 100 mL of purified water, and 7.9 g of benzoyl chloride was dropwise added thereto under ice-cooling. After stirring the mixture for 6 hours, hydrochloric acid was added to adjust the pH to 2 or less. The precipitated crude product was filtered, and then recrystallized with ethanol solution to give 8.7 g of the desired product.
