実験手順

630 mg of N-[(2S)-2-fluoropropyl]-N-[6-(methoxymethoxy)-2,3-dihydro-1H-inden-5-yl]-4-methyl-1,3-thiazole-2-sulfonamide was dissolved in 3.50 mL of methanol, and 1.50 mL of a 4 M hydrogen chloride/dioxane solution was added thereto, followed by stirring at room temperature for 6 hours. The reaction liquid was concentrated under reduced pressure, and to the obtained residue was added a saturated aqueous sodium hydrogen carbonate solution, followed by extraction with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous sodium sulfate, and then the solvent was evaporated to obtain 586 mg of N-[(2S)-2-fluoropropyl]-N-(6-hydroxy-2,3-dihydro-1H-inden-5-yl)-4-methyl-1,3-thiazole-2-sulfonamide.
