Like the traditional imidazole antibacterial product ketoconazole, ELUBIOL is a new broad-spectrum antifungal item of imidazole, which can prevent the biosynthesis of fungal ergosterol and change the make-up of various other lipid compounds in the cell membrane layer. It has antagonistic impacts on Candida, Cryptococcus neoformans, Histoplasma capsulatus, Blastomyces dermatitidis as well as Coccidioides, yet compared to ketoconazole, the latter can not be made use of in personal treatment items, while ELUBIOL water-soluble It is far better than ketoconazole, appropriate for usage in the field of personal treatment products, and has been consisted of in the scope of use of individual treatment items in Europe, with an extremely broad market prospect.

Preparation of ELUBIOL
The synthesis of ELUBIOL, in US Pat. 4-yl] Methanol p-toluenesulfonate (Ⅲ, active ester type) as raw material, obtained by condensation with 4-(4-hydroxyphenyl)-1-piperazine carboxylate ethyl ester (IV), the details are as follows:
In US4335125, ELUBIOL is recrystallized with 2-methyl-2-pentanone, and the obtained neoconazole has a melting point of 112.2°C. In the world patent WO93/18743, the synthesis of neoconazole is based on ketoconazole as the starting material. After hydrolysis and acylation, purification and crystal transformation to obtain type I neoconazole, the details are as follows:
Its purification is to crystallize with 2-methyl-2-pentanone, the reaction and crystallization yield is 84.9%, and then transform to type I with acetone, the yield of transformation is 82.1%, and the total yield of type I is 69.7%. Type I ELUBIOL has a melting point of 127.6°C.
In WO93/18743, the type I and type II properties of ELUBIOL are also mentioned. The DSC maximum peak of type I with high melting point is at 127.6°C, while the maximum DSC peak of type II with low melting point is at 110.9°C. The type is more stable, and it is preferentially used in cosmetics for the human body. In the above two patents, 2-methyl-2-pentanone is used for recrystallization, which is not only expensive and uneconomical, but also ketone chemicals remain in the product, which is harmful to human health. In the Chinese patent publication CN101665490A, it is mentioned that ethyl acetate is used for recrystallization, and the recrystallization yield is 69.8% to 84.5%. Ethyl acetate is used for recrystallization of organic matter, but the yield is not high, and the melting point of the product is not mentioned.
CN201210075893.7 provides a new method for purifying ELUBIOL. The steps of the technical solution are as follows:
Step (1). Dissolving the ELUBIOL crude product at a temperature of 5085° C. with a mixed solution of water and lower alkanol, the ratio of water and lower alkanol in the mixed solution is 3/71/19;
The low alkane alcohol in described step (1) comprises methyl alcohol, ethanol, propanol, Virahol; The weight ratio of the mixed solution of described water and lower alkane alcohol and ELUBIOL crude product is 10/12/ 1;
Step (2). In the mixed solution in which the ELUBIOL crude product is dissolved, add activated carbon for decolorization, filter to remove carbon, and cool to -515°C to crystallize; then filter and dry again, and the content of the obtained neoconazole essence is above 99.0%, HPLC The purity is above 99.5%, and the melting point is between 127.6 and 130°C.
