Provided is a method for amidating a hydroxy ester compound at a high chemical selectivity.nThe amidation reaction method for a hydroxy ester compound comprises, in the presence of a catalyst containing a compound of a transition metal of the group 4 or group 5 in the periodic table, reacting at least one kind of hydroxy ester compound selected from the group consisting of an α-hydroxy ester compound, a β-hydroxy ester compound, a γ-hydroxy ester compound and a δ-hydroxy ester compound with an amino compound so as to amidate an ester group having a hydroxyl group at the α-, β-, γ- or δ-position of the hydroxy ester compound. |
