Procedure
Substantially the same procedure as in Example 219 was repeated using a starting material, 7-methoxybenzofuran-2-carboxylic acid, and morpholine to give 7-methoxy-2-morpholinocarbonylbenzofuran (Compound 329a). Successively, it was formylated to give 4-formyl-7-methoxy-2-morpholinocarbonylbenzofuran (Compound 329b), then compound 329b was reacted with methylamine hydrochloride to give compound 329 as a white solid.
