Embodiment 1
[0308] Synthesis of 4-(4-Hydroxyphenylthiomethyl)-N-phenylbenzamide (Compound No.XII-248)
[0309] Into a 200 ml 4-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 sodium hydroxide, and 50 ml of methanol were added at room temperature. After confirming that potassium hydroxide was dissolved, the internal temperature was cooled to 10°C, 2.6 g (10.6 mmol) of 4-chloromethyl-N-phenylbenzamide was added, and the mixture was stirred at room temperature for 3 hours. After the reaction was completed and hydrochloric acid was formed, 50 ml of water was added, and the precipitated crystals were filtered to obtain 3.0 g of 4-(4-hydroxyphenylthiomethyl)-N-phenylbenzamide. The yield was 84%. The melting point is 220-222°C.
Embodiment 2
[0311] Synthesis of 4-(4-hydroxyphenylthiomethyl)-N-(2-hydroxyphenyl)benzamide (Compound No.XII-267)
[0312] Except using 4-chloromethyl-N-(2-hydroxyphenyl)benzamide to replace 4-chloromethyl-N-phenylbenzamide in Example 1, carry out the same reaction as in Example 1 . The melting point is 152-156°C.
Embodiment 3
[0314] Synthesis of 4-(4-hydroxyphenylthiomethyl)-N-(3-hydroxyphenyl)benzamide (Compound No.XII-264)
[0315] The same reaction as in Example 1 was carried out except that 4-chloromethyl-N-(3-hydroxyphenyl)benzamide was used instead of 4-chloromethyl-N-phenylbenzamide in Example 1. The melting point is 218-222°C.
