摘要:
A method for manufacturing a 6-substituted 1-methyl-1H-benzimidazole derivative represented by the formula (IV) wherein R3 represents a hydrogen atom or a C1-C4 alkyl group. A 4-substituted N2-methylbenzene-1,2-diamine derivative is prepared from a particular 5-substituted N-methyl-2-nitroaniline derivative, subsequently reacting the resulting compound with {4-[(2,4-dioxo-1,3-thiazolidin-5-yl)methyl]phenoxy}acetic acid or an acid chloride or a mixed acid anhydride thereof, and subsequently subjecting the resulting compound to intramolecular dehydration condensation. A compound of the formula (II) wherein R1 represents a hydrogen atom, a C1-C4 alkyl group, or a protective group for the nitrogen atom, and R2 represents a hydrogen atom or a protective group for the nitrogen atom is prepared and used as an intermediate.
