Reaction Conditions

Reaction Steps

In a 200 ml four-necked flask equipped with a stirrer and a thermometer, 1.34 g (10.6 mmol) of 4-mercaptophenol, 0.7 g (10.6 mmol) of potassium hydroxide and 50 ml of methanol were added at room temperature. After confirming that potassium hydroxide has been dissolved, the inner temperature was cooled to 10° C. and 2.6 g (10.6 mmol) of 4-chloromethyl-N-phenylbenzamide was added, followed by stirring at room temperature for 3 hours. After the completion of the reaction, the reaction solution was acidified with hydrochloric acid and 50 ml of water was added, and then the deposited crystal was collected by filtration to obtain 3.0 g of 4-(4-hydroxyphenylthiomethyl)-N-phenylbenzamide. The yield was 84%. The melting point was 220–222° C.
