Reaction Steps

In the same manner as in Starting Material Synthesis Example 4 and using ethyl 2-aminobenzo[b]thiophene-3-carboxylate (3 g), 3-fluoro-4-nitrotoluene (2.1 g) and dimethyl sulfoxide (25 ml), ethyl 2-(5-methyl-2-nitroanilino)benzo[b]thiophene-3-carboxylate (5.4 g) was obtained. Without purification, in the same manner as in Starting Material Synthesis Example 19 and using 10% palladium-carbon (1.5 g), ethyl 2-(2-amino-5-methylanilino)benzo[b]thiophene-3-carboxylate (1.6 g) was obtained.
