Method of removing dibenzofulvene and/or a dibenzofulvene amine adduct from a reaction mixture obtained by reacting an amino acid compound protected with an Fmoc group with an amine for deprotection, include stirring and partitioning the reaction mixture in a hydrocarbon solvent and a polar organic solvent, and removing a resulting hydrocarbon solvent layer in which the dibenzofulvene and/or the dibenzofulvene amine adduct is dissolved. The hydrocarbon solvent may have a carbon number of at least 5; the polar organic solvent may be free from organic amide solvents; and the polar organic solvent may immiscible with the hydrocarbon solvent.
