Abstract
This invention relates to a method of preparing a benzoimidazole derivative at high purity and high yield so as to enable the production of the benzoimidazole derivative compound as an antagonist against a vanilloid reactor-1, and particularly to a method of preparing a benzoimidazole derivative at high purity and high yield, wherein the benzoimidazole derivative is synthesized using a novel intermediate, namely, benzaldehyde, and thereby the preparation process is simple so that it can be applied to production.
