Reaction Steps

A mixture of 7-nitro-1H-indole-2-carbothioamide (2.06 g), 2-bromo-1,1-diethoxyethane (3.67 g), ethanol (10 mL) and N,N-dimethylacetamide (10 mL) was stirred at 100° C. for 4 hr. To the reaction mixture was added water, and the resulting crystals were filtrated, washed with water and hexane, and dried to give the title compound (2.21 g, yield 97%) as yellow crystals. melting point 130-131° C.
