실험 절차
A mixture N-(5-Bromo-3-methoxy-2-pyrazinyl)-5-chloro-2-thiophenesulphonamide (Example 1) (0.40 g), diisopropylethylamine (0.26 g) and [2-(chloromethoxy)ethyl]trimethylsilane (0.25 g) in dichloromethane (50 mL) was stirred at room temperature. After 2 h, the solution was washed with water, dried (MgSO4) and evaporated. Chromatography on silica gel eluting with ethyl acetate/isohexane mixtures gave the title compounds a white solid (0.40 g).
