89% | With potassium carbonate In N,N-dimethyl-formamide at 60℃; for 15 h; | General procedure: To a stirred solution of compound 1a-1n (9.90 mmol) in DMF (20 mL) were added methyl thioglycolate (10.9 mmol) and potassium carbonate (39.6 mmol). The resulting mixture was stirred at 60 °C for 15 h. The DMF was removed under reduced pressure,water (50 mL) was added and the mixture was extracted with ethylacetate (2 x 40 mL). The combined organic layers were dried withsodium sulfate, filtered, and the solvents were removed under reduced pressure to afford the title compound 2a-2n [31,34]. 4.1.1.1. Methyl 4-bromobenzo[b]thiophene-2-carboxylate (2a).Yield 89percent, white solid; m. p. 77-78 °C; 1H NMR (600 MHz,DMSO?d6) δ 8.12 (d, J = 8.2 Hz, 1H), 8.01 (d, J = 0.6 Hz, 1H), 7.73 (d,J = 7.7 Hz, 1H), 7.46 (t, J = 7.9 Hz, 1H), 3.91 (s, 3H). |
