Procedure
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. monoleate in this order. To the solution was added the distilled water for injection to obtain a desired final volume. The resulting solution was filtered through an appropriate filter paper and sterilized. 1 ml of the thus prepared solution was filled into each ampul to prepare an injection.
Workup
- customto the same hydrolysis as in Example 147
