実験手順

A mixture of 5-(2-methoxyethoxy)-7-[(pyridin-2-ylsulfonyl)amino]-1H-indole-2-carboxylic acid (4.24 g), 2-(benzylthio)-3,3-dimethoxypropan-1-amine (2.88 g), 1H-1,2,3-benzotriazol-1-ol (1.80 g), N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (2.70 g) and N,N-dimethylformamide (40 mL) was stirred at room temperature for 3 days. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4), and concentrated. The obtained residue was subjected to silica gel column chromatography, and eluted with hexane-ethyl acetate (2:3-1:4, volume ratio) to give the title compound (6.03 g, yield 91%) as a colorless amorphous solid.
