실험 절차

3-Amino-N-(2,4-dichlorophenyl)-6-methoxybenzofuran-2-carboxamide ¼ hydrate (0.9 g) obtained in Example 1 was dissolved in dichloromethane (10 ml) and chlorosulfonyl isocyanate (0.4 g) was added under ice-cooling. The mixture was further stirred at room temperature for 1 hr. Then water was added and the precipitated crystals were recrystallized from water-containing dimethylformamide to give the title compound (0.3 g). melting point: >260° C.
