<p>A dibenzofulvene amine adduct is removed by contacting a reaction mixture containing the dibenzofulvene amine adduct, which is obtained by reacting, for deprotection, an amino acid compound protected with an Fmoc group with an amine compound wherein a nitrogen atom has at least one hydrogen atom, with carbon dioxide, and removing the carbonate of the dibenzofulvene amine adduct. Alternatively, a dibenzofulvene amine adduct is removed by mixing a reaction mixture during a deprotection reaction of the amino acid compound protected with an Fmoc group, or after the reaction with an amine compound wherein a nitrogen atom has at least one hydrogen atom to give a mixture containing the dibenzofulvene amine adduct, contacting the mixture with carbon dioxide, and removing the carbonate of the dibenzofulvene amine adduct.</p> |
