摘要:An N-alkoxymethyl benzamide derivative represented by Formula (I); (I) (In the formula, reference X indicates a halogen atom, references Y1 and Y2 indicate hydrogen atoms or halogen atoms, and may be identical or different, and reference R indicates a lower alkyl group.) and a manufacturing method for this N-alkoxymethyl benzamide derivative in which a substituted benzamide and an alpha -haloacetal are reacted. Furthermore, a manufacturing method for benzamide derivatives in which the N-alkoxymethyl benzamide derivative represented by Formula (I) above and benzene or a derivative thereof are reacted, and a benzamide derivative is produced. The N-alkoxymethyl benzamide derivative of the present invention is a novel compound, and possesses utility as an intermediate in the manufacturing of oxazoline derivatives which possess insecticidal and anti-mite activity, and as a starting material for the synthesis of various organic compounds and the like.
