PROBLEM TO BE SOLVED: To provide a means for improving the productivity of an N-alkylborazine, by solving the problems wherein deposit attaches to a cooling part of a distilling device during the distillation and purification after synthesis, in the production thereof. SOLUTION: Disclosed is a method for producing N-alkylborazine which includes a step of synthesizing the N-alkylborazine by reacting an alkali borohydride represented by ABH<SB>4</SB>(wherein, A is a lithium atom, a sodium atom or a potassium atom) with an amine salt represented by (RNH<SB>3</SB>)<SB>n</SB>X (wherein, R is an alkyl group; X is a sulfate group or a halogen atom; and n is 1 or 2) in a solvent, wherein the method comprises a step of purifying the N-alkylborazine by distilling a solution containing the N-alkylborazine at a distillation temperature not higher than the temperature by 15°C higher than the standard boiling point of the N-alkylborazine.
