ABSTRACT Because fluazinam is excellent as an active ingredient of pesticides and highly useful, it is desired to produce it efficiently in a proper form with simple operations at low cost in an environmentally friendly manner. The desired product is obtained in good yields with simple operations by using industrially advantageous reaction systems by a process comprising (1) a step of reacting ACTF and DCDNBTF in the presence of an alkali component, a solvent selected from the group consisting of ethers, nitriles and esters, (2) a step of neutralizing or acidifying the reaction mixture with an acid and (3) a step of removing the solvent by distillation from the mixture containing fluazinam as the reaction product and the solvent to precipitate crystals of the product.
