実験手順
5-Ethoxycarbonyl-2-(α-bromoacetyl)thiazole and 3,4-diethoxythiobenzamide were subjected to the same reaction as in Example 1 and then to the same hydrolysis as in Example 147 to obtain 2-(3,4-diethoxyphenyl)-4-(5-carboxy-2-thiazolyl)thiazole.
後処理
- customto the same hydrolysis as in Example 147
