YieldReaction ConditionsOperation in experiment
54% With triethylamine; In acetonitrile; at 25℃; for 19.0h; Methyl 3-amino-6-nitrobenzothiophene-2-carboxylate: Methyl thioglycolate (0.08 mL, 0.85 mmol) was added to a solution of <strong>[34667-88-4]2-fluoro-4-nitrobenzonitrile</strong> (145 mg, 0.87 mmol), and triethylamine (0.14 mL, 1.0 mmol) in acetonitrile (20 mL) stirred under nitrogen at 25° C. After 3 hours further triethylamine (0.28 mL, 2.0 mmol) was added to the solution, which was stirred at 25° C. for a further 16 hours. The solvent was removed under reduced pressure to give a brown residue, which upon trituration with chloroform precipitated methyl 3-amino-6-nitrobenzothiophene-2-carboxylate (103 mg, 54percent) as a red brown solid, mp 228.5-229.5° C. 1H NMR (DMSO-d6): delta 8.87 (d, J=2.0 Hz, 1H), 8.32 (d, J=9.0 Hz, 1H), 8.15 (dd, J=8.8, 2.0 Hz, 1H), 7.26 (brs, 2H), 3.77 (s, 3H). Mass Spectrum (CI): 253 (100, MH+), 252 (52, M+).
