Procedure
Substantially the same procedure as in Example 219 was repeated using a starting material, 7-methoxybenzofuran-2-carboxylic acid, and cyclobutylamine to give N-Cyclobutyl-7-methoxybenzofuran-2-carboxamide (Compound 289a). Successively, it was formylated to give N-cyclobutyl-4-formyl-7-methoxybenzofuran-2-carboxamide (Compound 289b), then compound 289b was reacted with methylamine hydrochloride to give Compound 289 as a white solid.
