PROBLEM TO BE SOLVED: To provide a method for producing 2-amino-4,6-di-substituted 1,3,5-triazine simply and under a mild condition. SOLUTION: Guanidine or a salt thereof is added to a mixture including a nitrile compound and a base and reacted therewith to produce 2-amino-4,6-di-substituted 1,3,5-triazine. Alternatively, a mixture (or a mixed liquid) including guanidine or a salt thereof and a solvent may be added to a mixture (or a mixed liquid) including a nitrile compound, a base and a solvent and reacted therewith. The base may be an alkali metal hydride, for example, sodium hydride. After completing the reaction, a step of depositing a deposit by adding a poor solvent to the reaction mixture and a step of separating the deposited deposit may be included.
