실험 절차

133 mg of N-[(2S)-2-fluoropropyl]-N-(6-hydroxy-2,3-dihydro-1H-inden-5-yl)-4-methyl-1,3-thiazole-2-sulfonamide, 94.4 mg of tributylphosphine, and 71.5 mg of ethyl 5-(hydroxymethyl)pyridine-2-carboxylate were dissolved in 1.33 mL of THF, and 118 mg of 1,1′-[(E)-diazene-1,2-diyldicarbonyl]dipiperidine was added thereto, followed by stirring overnight at room temperature. After the insoluble materials were removed by filtration, the solvent was concentrated under reduced pressure and the obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=80:20) to obtain 116 mg of ethyl 5-{[(6-{[(2S)-2-fluoropropyl][(4-methyl-1,3-thiazol-2-yl)sulfonyl]amino}-2,3-dihydro-1H-inden-5-yl)oxy]methyl}pyridine-2-carboxylate.
