EXAMPLE 6 Synthesis of potassium 3,4-dichloroisothiazole-5-carboxylate (Compound No. 7) Potassium hydroxide (0.27 g) dissolved in 3 ml of water was added to a solution of 3,4-dichloroisothiazole-5-carboxylic acid (0.95 g) in 4 ml of ethanol. The solvent was distilled off under reduced pressure. The crystals thus obtained were washed with a small quantity of ethanol.
With the rapid development of chemical substances, we look forward to future research findings about 18480-53-0
