Reaction Steps

To a solution of 2-formyl-N-methyl-N-[2-(1,3-thiazol-2-yl)-1H-indol-7-yl]thiophene-3-sulfonamide (790 mg) in tetrahydrofuran (20 mL) was added methylmagnesium bromide (3.0 M, 1.5 mL), and the mixture was stirred at room temperature for 1 hr. 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 residue was subjected to silica gel column chromatography (ethyl acetate:hexane=1:1) to give the title compound (272 mg, yield 33%) as white crystals. melting point 193° C.
