Procedure
A mixture of ethyl 1-(methoxymethyl)-7-[(2-thienylsulfonyl)amino]-1H-indole-2-carboxylate (1.03 g), methyl iodide (0.24 mL), potassium carbonate (0.36 g) and N,N-dimethylformamide (10 mL) was stirred at room temperature overnight. Water was added to the reaction mixture, and the obtained crystals were filtrated, washed with water and dried to give the title compound (1.06 g, yield 99%) as colorless crystals. melting point 143-145° C.
