- Synthesis method of high-purity bacteriostatic agent and derivatives thereof
-
The invention discloses a synthesis method of a high-purity bacteriostatic agent and derivatives thereof. The synthesis method comprises the following specific steps: adding primary amine or secondaryamine into a solvent, adding perchloromethyl mercaptan, reacting at room temperature for 14-18 hours, washing the reaction solution with water, separating, drying, concentrating the solvent and separating to obtain an intermediate 1; mixing the intermediate 1 with a solvent and fluoride, heating to 100-140 DEG C, reacting for 6-18 hours, filtering the reaction solution, washing with water, drying, concentrating the solvent, rectifying and separating to obtain an intermediate 2; mixing the intermediate 2 with a solvent, introducing hydrogen chloride gas at 0-10 DEG C to react for 2-16 hours, washing the reaction solution with water, separating, drying and concentrating the solvent to obtain an intermediate 3; and mixing the intermediate 4 with a solvent, adding alkali at 0-10 DEG C, reacting for 0.5-1 hour, adding the intermediate 3, reacting at room temperature for 1-2 hours, washing the reaction solution with water, separating, drying and concentrating the solvent to obtain the target compound. The method is low in cost and high in product yield and a high-purity product can be obtained.
