실험 절차

Substantially the same procedure as in Example 219 was repeated using a starting material, 7-methoxybenzofuran-2-carboxylic acid, and p-anisidine to give N-(4-methoxyphenyl)-7-methoxybenzofuran-2-carboxamide (Compound 399a). Successively, it was formylated to give N-(4-methoxyphenyl)-4-formyl-7-methoxybenzofuran-2-carboxamide (Compound 399b), then compound 399b was reacted with cyclobutylamine to give compound 399 as a white solid.
