실험 절차

To a solution of the above carboxylic acid (900 mg) in DMF was added EDC (1.2 eq) and HOBT (1.2 eq). After stirring for 10 min, N-(3-amino-5-tert-butyl-2-methoxy-phenyl)-methanesulfonamide (1.0 eq) was added. The suspension was stirred at room temperature for 48 h. The DMF was removed in vacuo and the resulting oil was dissolved in EtOAc, washed with water three times, followed by saturated NaHCO3 solution and brine. The organics were dried over MgSO4, filtered and concentrated to give a crude yellow solid which was triturated with 30% EtOAc/hex (small amount) and filtered to provide 7-nitro-benzo[b]thiophene-2-carboxylic acid (5-tert-butyl-3-methanesulfonylamino-2-methoxy-phenyl)-amide as a bright yellow solid (1.4 g, 72%).
