실험 절차

A reaction mixture of N,N-dimethyl-7-(piperazin-1-yl)benzofuran-2-carboxamide (0.090 g, 0.33 mmol) (Example 39d), 2-(6-methoxypyridin-2-yl)ethyl 4-methylbenzenesulfonate (0.10 g, 0.33 mmol) and potassium carbonate (0.046 g, 0.33 mmol) in dry acetonitrile (10 mL) was heated at 80° C. for over night. After cooling, the mixture was filtered and the solvent removed in vacuo. The product was purified by preparative HPLC to give the title compound. Yield: 0.048 g (36%).
