실험 절차

To a solution of methyl 4-{[(5-chloro-1,3-thiazol-2-yl)amino]sulfonyl}benzoate (Preparation 3, 3.2 g, 9.6 mmol, 1 eq) in dioxane (20 ml) was added a 2M solution of lithium hydroxide (20 ml) and the reaction mixture stirred at room temperature for 2 hours. The reaction mixture was diluted with water, washed with ethyl acetate and then acidified with concentrated HCl. The resulting precipitate was collected by filtration to yield the title compound as a light brown solid (3.0 g, 9.0 mmol, 98%).
