実験手順

To a solution of N,O-dimethylhydroxylamine hydrochloride (48 mg) in N,N-dimethylformamide (10 mL) was added triethylamine (85 uL) under ice-cooling, and the mixture was stirred for 10 min under ice-cooling. (2-{7-[[(2-Methoxyphenyl)sulfonyl](methyl)amino]-1H-indol-2-yl}-4,5-dihydro-1,3-thiazol-5-yl)acetic acid (200 mg), 1H-1,2,3-benzotriazol-1-ol (90 mg) and N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (130 mg) were added to the mixture, and the mixture was stirred from under ice-cooling to room temperature for 15 hr. The reaction solution was diluted with ethyl acetate, washed with water, aqueous sodium hydrogencarbonate solution and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was subjected to silica gel column chromatography (ethyl acetate:methanol=100:0-95:5) to give the title compound (180 mg, yield: 85%) as a pale-yellow amorphous solid. MS:489(MH+).
