Procedure

Substantially the same procedure as in Example 219 was repeated using a starting material, 7-Methoxybenzofuran-2-carboxylic acid, and piperidine to give 2-piperidinocarbonyl-7-methoxybenzofuran (Compound 319a). Successively, it was formylated to give 2-piperidinocarbonyl-4-formyl-7-methoxybenzofuran (Compound 319b), then compound 319b was reacted with methylamine hydrochloride to give compound 319 as a white solid.
