20699-85-8, Methyl 5-aminobenzo[b]thiophene-2-carboxylate is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
] A mixture of 500 mg of methyl 5-aminobenzo[b] thiophene-2-carboxylate, 323 mg of acetic anhydride, 623 mg of diisopropylethylamine, and 10 ml of dichloromethane was stirred for 4 hours at room temperature. The reaction mixture was washed with an aqueous saturated sodium hydrogen carbonate solution and saturated saline, dried over magnesium sulfate, and concentrated under reduced pressure. The residues were subjected to silica gel colunm chromatography, thereby obtaining 449 mg of methyl 5-(acetylamino) benzo[b]thiophene-2-carboxylate (hereinafier, described as a ?compound 67 of the present invention?).12238] Compound 67 of the Present InventionHj2239] ?H-NMR (CDC13) oe: 8.22-8.21 (m, 1H), 7.99 (s, 1H), 7.78-7.76 (m, 1H), 7.44-7.40 (m, 2H), 3.94 (s, 3H), 2.22 (s, 3H).
