  • Patent number: 12018010
    Abstract: The present invention relates to a novel method for preparing efinaconazole using an ionic liquid as a medium. The method includes subjecting 1-[[(2R,3S)-2-(2,4-difluorophenyl)-3-methyloxiranyl]methyl]-1H-1,2,4-triazole to a coupling reaction with 4-methylenepiperidine or an organic chemically acceptable salt thereof in the presence of a base and an ionic liquid compound. The base makes the 4-methylenepiperidine or organic chemically acceptable salt thereof anionic. The use of the ionic liquid in the method of the present invention prevents the formation of related substances, shortens the reaction time, and enables easy preparation of the final compound efinaconazole in high purity and yield on a large scale, compared to the use of organic solvents in conventional methods.

  • Publication number: 20230047729
    Abstract: Proposed is a novel method for preparing liraglutide by means of an ionic liquid and a eutectic solvent, which are environment-friendly solvents. More specifically, the method is characterized in that fractionated peptide 1 represented by the following formula (1) and fractionated peptide 2 represented by the following formula (2) are subjected to a coupling reaction in the presence of an ionic liquid or a eutectic solvent. In preparing GLP-1 analogues such as liraglutide, the present method increases reactivity when producing liraglutide, which is an unprocessed reactant, by using an ionic liquid and a eutectic solvent as environment-friendly solvents instead of using organic solvents. Accordingly, through a relatively short and simple purification process, the present method has advantages of reducing the formation of related substances, improving purity, improving yields, shortening reaction times, reducing production cost, and lowering the manufacturing cost.

  • Patent number: 11529317
    Abstract: There is provided a method of preparing silica nanocapsules, the method comprising mixing a surfactant with water at a temperature that is above the gel-to-liquid transition temperature of the surfactant to form a mixture, passing the mixture one or more times through at least one pore to obtain a dispersion of vesicles, and adding a silica precursor to the dispersion of vesicles to form silica nanocapsules. Also provided is a silica nanocapsule formed from a vesicle template, and a method of delivering one or more types of molecules to a subject. In a specific embodiment, hollow silica nanocapsules having substantially lens-shaped are synthesized by employing dimethyldioctadecylammonium bromide (DODAB) or dioctadecyldimethyl ammonium chloride (DODAC) as the vesicle template and tetraethyl orthosilicate (TEOS) as the silica precursor.
