To provide an industrially useful method of producing 2-hydroxyethyloxyamine compound.

The method of producing a 2-hydroxyethyloxyamine compound represented by formula (3) includes reacting a 2-(2-hydroxyethoxy)isoindoline-1,3-dione compound represented by formula (1) with a primary amine represented by formula (2) (in the formulae, R1, R2 each independently represent a hydrogen atom, or a 1-4C alkyl group, provided that at least either R1 or R2 represents a 1-4C alkyl group; and R3 represents a hydrogen atom, a 1-10C alkyl group, a 1-8C alkoxyl group, a hydroxyl group, a phenyl group, or a benzyl group).
