Versuchsvorschrift

To a solution of N-[2-(5-{2-[(2-hydroxyethyl)amino]ethyl}-4,5-dihydro-1,3-thiazol-2-yl)-1H-indol-7-yl]-N-methylthiophene-2-sulfonamide (220 mg) in ethanol (2 mL) and water (1 mL) were added chloroacetyl chloride (95 μL) and 8M aqueous sodium hydroxide solution (310 μL), and the mixture was stirred at the inside temperature of 20° C. or less for 3 hr. 1M Hydrochloric acid was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium hydrogencarbonate and saturated brine, dried (MgSO4), and concentrated. The residue was subjected to silica gel column chromatography to give the title compound (100 mg, yield 41%) as a colorless amorphous solid from a fraction eluted with ethyl acetate-methanol (10:1, volume ratio).
