Procedure

Substantially the same procedure as in Example 219 was repeated using a starting material, 7-methoxybenzofuran-2-carboxylic acid, and 4-chloroaniline to give N-(4-chlorophenyl)-7-methoxybenzofuran-2-carboxamide (Compound 379a). Successively, it was formylated to give N-(4-chloropheny)-4-formyl-7-methoxybenzofuran-2-carboxamide (Compound 379b), then compound 379b was reacted with cyclobutylamine to give compound 379 as a white solid.
