Procedure
Substantially the same procedure as in Example 219 was repeated using a starting material, 7-Methoxybenzofuran-2-carboxylic acid, and cyclopentylamine to give N-cyclopentyl-7-methoxybenzofuran-2-carboxamide (Compound 299a). Successively, it was formylated to give N-cyclopentyl-4-formyl-7-methoxybenzofuran-2-carboxamide (Compound 299b), then compound 299b was reacted with methylamine hydrochloride to give compound 299 as a white solid.
