Tetrahydrofuran → N-{2-[5-(chloromethyl)-1,3-thiazol-2-yl]-1H-indol-7-yl}-N-methylthiophene-2-sulfonamide

Participants

Reaction Steps

A mixture of N-{2-[5-(hydroxymethyl)-1,3-thiazol-2-yl]-1H-indol-7-yl}-N-methylthiophene-2-sulfonamide (0.10 g), thionyl chloride (0.03 mL), N,N-dimethylformamide (1 drop) and tetrahydrofuran (6 mL) was stirred at room temperature overnight. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, aqueous sodium bicarbonate, and saturated brine in this order, dried (MgSO4) and concentrated to give the title compound (0.08 g, yield 76%) as yellow crystals. melting point 204-205° C.
