Disclosed is a method for producing an optically active trans-2-aminocyclohexanol which is characterized in that a trans-2-aminocyclohexanol in a racemic form and an optically active 2-methoxyphenyl acetic acid are reacted and then an optically active 2-methoxyphenyl acetate of a thus-obtained optically active trans-2-aminocyclohexanol is separated. Also disclosed is an optically active 2-methoxyphenyl acetate of an optically active trans-2-aminocyclohexanol. This method enables to produce an optically active trans-2-aminocyclohexanol from a commercially advantageous low-cost material by a simple process with high yield.

La présente invention concerne un procédé de production du trans-2-aminocyclohexanol optiquement actif qui est caractérisé en ce que le trans-2-aminocyclohexanol dans une forme racémique et l'acide 2-méthoxyphényl acétique sont mis en réaction et ensuite le 2-méthoxyphényle acétate du trans-2-aminocyclohexanol optiquement actif ainsi obtenu est séparé. L'invention concerne également le 2-méthoxyphényle acétate optiquement actif du trans-2-aminocyclohexanol optiquement actif. Ce procédé permet de produire le trans-2-aminocyclohexanol optiquement actif à partir d'une substance à bas prix commercialement avantageuse par un procédé simple avec un rendement élevé.
