Potassium Hydroxide → HCID 21980165, compound

Participants

Reaction Steps

To methyl (2-{[(3-chloro-2-methylphenyl)sulfonyl]amino}-1,3-thiazol-5-yl)acetate (Example 2) (0.2 g, 0.55 mmol) dissolved in EtOH (5.5 mL) was added aqueous KOH (0.6 mL, 5.5 M). The reaction mixture was stirred at room temperature for 1 h. The solvent was then removed under reduced pressure and the crude product dissolved in water. The aqueous phase was acidified using conc. HCl so that the product precipitated. Filtration and washing with water (5 mL) afforded 0.2 g, 97% product. The product was used without any further purification.
