It is intended to provide a method of producing a pyrrole-imidazole polyamide whereby a longer pyrrole-imidazole polyamide can be conveniently synthesized and a peptide (protein) can be easily transferred. According to this method, a pyrrole-imidazole polyamide having a carboxylate group which can be excised from a solid phase carrier at its end, makes it possible to directly transfer various functional groups and can exactly distinguish DNA sequences can be efficiently produced. A method of synthesizing a pyrrole-imidazole polyamide characterized by performing automatic synthesis by the solid phase Fmoc method with the used of a peptide synthesizer; a pyrrole-imidazole polyamide having a carboxyl group at its end obtained by this method; a pyrrole-imidazole polyamide having a DNA alkylation agent transferred into the carboxyl group at the end of the above-described pyrrole-imidazole polyamide; and a sequence-specific DNA alkylation method characterized by using the above compound.
