Paragraph 0080-0082, (2017/08/18)
The invention discloses a method for preparing (3S)-3-amino-2-hydroxyl-N-cyclopropylhexanamide. The compound can be used as an important intermediate for preparing telaprevir. According to the invention, ethyl butyrylacetate is used as a starting raw material, and through steps of helogenation, substitution, amination, reduction, hydrolysis, deprotection, resolution and the like, (3S)-3-amino-2-hydroxyl-N-cyclopropylhexanamide is prepared. The method provided by the invention has advantages as follows: raw materials are cheap and easily available; reaction yield is high; and costs are high.

Page/Page column 65, (2008/06/13)
The present invention relates to compounds that inhibit serine protease activity, particularly the activity of hepatitis C virus NS3-NS4A protease. As such, they act by interfering with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The invention further relates to compositions comprising these compounds either for ex vivo use for administration to a patient suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a patient by administering a composition comprising a compound of this invention. The invention further relates to processes for preparing these compounds.
