実験手順
10 Grams of DL-tryptophane was dissolved in a mixture of 100 ml of acetone with 20 ml of water, then to this solution was added 6 g of potassium carbonate. Under an ice-cooled condition, 9 g of 4-chlorobenzoyl chloride was added dropwise to the above-mentioned mixture, and the reaction mixture was stirred at the same temperature for 2 hours. Then, acetone was removed by evaporation, to the residue thus obtained was added water, and mixture was acidified by adding concentrated hydrochloric acid, the crystals formed were collected by filtration, and washed with water. Recrystallized from ethanol to obtain 14 g of 2-(4-chlorobenzoylamino)-3-(indol-3-yl)propionic acid. White powdery substance.
