  • Patent number: 11919884
    Abstract: A method for preparing voriconazole L-camphorsulphonate and voriconazole. The method for preparing voriconazole L-camphorsulphonate comprises: method 1: dissolving (2R,3S)/(2S,3R) isomer mixture and L-camphor sulphonic acid in water and acetone, and performing crystallisation filtration to obtain voriconazole L-camphorsulphonate; method 2: (a) dissolving a mixture of isomer mixture and L-camphor sulphonic acid in a first solvent and then performing crystallisation filtration; or (a?) dissolving L-camphorsulphonate of the isomer mixture in a first solvent and then performing crystallisation filtration; (b) concentrating the filtrate obtained in step (a) or (a?) into a solid; and (c) dissolving the solid obtained in step (b) in a second solvent and performing crystallisation filtration to obtain voriconazole L-camphorsulphonate. Adjusting the resolution solvent effectively reduces production costs and facilitates recycling of the resolution solvent.
