実験手順
A 250 mL one-necked flask was charged with 18.3 grams of isatin (0.124 mol), 37.1 mL. of 30% potassium hydroxide (0.196 mol) and 50 mL of water. The mixture was stirred at room temperature for 6 hours. At the end of this time, the pH of the mixture was adjusted to 7.36 by the addition of 10% hydrochloric acid. Water was removed from the mixture by means of a rotary evaporator, and the crude potassium 2-aminophenylglyoxylate obtained in this manner was dried in a desicator. The crude, dried material weighed 22.1 grams, indicating a yield of 87 percent.
