실험 절차

To a solution of N-{2-[5-(2-chloroethyl)-4,5-dihydro-1,3-thiazol-2-yl]-1H-indol-7-yl}-N-methylthiophene-2-sulfonamide (100 mg) in N,N-dimethylformamide (3 mL) were added potassium carbonate (65 mg) and ethyl mercaptoacetate (50 μL), and the mixture was stirred overnight at 50° C. Potassium carbonate (20 mg) was added to the reaction mixture, and the mixture was stirred at 50° C. for 3 hr, and cooled to room temperature. The reaction mixture was diluted with ethyl acetate, washed with water and saturated brine, dried (MgSO4), and concentrated. The residue was subjected to silica gel column chromatography to give the title compound (60 mg, yield 50%) as a colorless amorphous solid from a fraction eluted with ethyl acetate-hexane (1:1, volume ratio). MS: 524 (MH+).
