Reaction Steps
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 overnight at room temperature. Water was added to the reaction mixture, and the resulting crystals were collected by filtration, washed with water, and dried to give the title compound (1.06 g, yield 99%) as colorless crystals. melting point 143-145° C.
