実験手順

137 mg of N-[(2S)-2-fluoropropyl]-N-(6-hydroxy-2,3-dihydro-1H-inden-5-yl)-4-methyl-1,3-thiazole-2-sulfonamide was dissolved in 1.05 mL of DMF, and 139 mg of ethyl 2-(bromomethyl)-1,3-thiazole-5-carboxylate and 102 mg of potassium carbonate were added thereto, followed by stirring at room temperature for 2 hours. To the reaction liquid was added water, followed by extraction with ethyl acetate. The organic layer was washed with water and saturated brine, and then dried over anhydrous sodium sulfate. The solvent was concentrated under reduced pressure and the obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:1) to obtain 154 mg of ethyl 2-{[(6-{[(2S)-2-fluoropropyl][(4-methyl-1,3-thiazol-2-yl)sulfonyl]amino}-2,3-dihydro-1H-inden-5-yl)oxy]methyl}-1,3-thiazole-5-carboxylate.
