The present invention belongs to the technical field of preparation methods of anti-hepatitis C virus drugs. The structural formula of a compound F-2 disclosed in the invention is as follows. The compound is easy to prepare, the preparation method is easy to operate, and the yield of the compound is high. The compound can be used for synthesis of an anti-hepatitis C virus drug Boceprevir, and a new concept and a new method for synthesis of the anti-hepatitis C virus drug Boceprevir can be provided. Compared with the existing synthesis method, the compound prepared by the preparation method can be more conveniently detected due to ultraviolet chromophoric groups in the molecule of the compound, introduction of a benzyl group to a hydroxyl group avoids side reactions in a condensation step which are caused by hydroxyl nucleophilicity, and thus the preparation method has certain advantages over the existing synthesis method.

The invention relates to the technical field of a preparing method of an anti-hepatitis C medicine Boceprevir. A compound VIII (B) provided by the invention has a structural formula shown as the attached drawing. The operation of the compound preparation is simple and convenient, and the yield is higher. The compound can be used for synthesizing the anti-hepatitis C medicine Boceprevir, and a new thought and method can be provided for synthesis of the anti-hepatitis C medicine Boceprevir. In addition, as ultraviolet chromophoric groups are contained in molecules of the compound, the detection is more convenient than that of an ordinary synthesis method, and side reaction caused by oxhydryl nucleophilicity in a condensation step is avoided through the introduction of benzyls on oxhydryls. Compared with the synthesis method in the prior art, the preparing method provided by the invention has certain advantages.

The present invention relates to the technical field of a method for preparation of an anti-HCV drug Boceprevir. The present invention provides compounds F of a formula as follows. The preparation of the compounds is simple and of high yield. The compounds can be used for synthesis of the anti-HCV drug Boceprevir. The present invention provides new implication and approach for the synthesis of the anti-HCV drug Boceprevir. Furthermore, a UV chromophore of the compounds makes the compounds more convenient to detect than compounds prepared by a conventional synthetic method, and introduction of a benzyl group to a hydroxyl group avoids side reactions during a condensation step due to the nucleophilicity of the hydroxyl group. There are certain advantages compared to an existing synthesis synthetic method.
