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.
