92% | With triethylamine; In dimethyl sulfoxide; at 25℃; for 0.5h; | NEt3 (0.16 mL, 1.15 mmol) was added dropwise to a solution of <strong>[34662-24-3]2-chloro-3-nitrobenzonitrile</strong> (191 mg, 1.05 mmol), and methyl thioacetate (0.1 mL, 1.1 mmol) in DMSO (3 mL) at 25 C. stirring under N2. The color of the solution turned dark orange. Thirty minutes later the reaction was quenched with ice water. The formed solid was collected by Buchner filtration and air dried to give methyl 3-amino-7-nitrobenzothiophene-2-carboxylate as a red-orange solid (244 mg, 92%). 1H NMR [(CD3)2SO]: delta 8.67 (dd, J=8.1, 1.0 Hz, 1H, H6), 8.58 (dd, J=7.8, 0.8 Hz, 1H, H4), 7.72 (t, J=7.8 Hz, 1H, H5), 7.37 (brs, 2H, NH2). |
