실험 절차

Synthesized as described for 52 using commercially available 4-n-butylbenzenesulfonyl chloride (0.47 g; 2 mmol), methyl 3-aminothiophene-2-carboxylate (314 mg; 2 mmol), pyridine (0.2 mL; 2.4 mmol), and anhydrous dichloromethane (10 mL). This afforded the title compound as a clear oil which later solidified (0.6 g).
