Title:
OPTICAL RESOLUTION WHICH OBTAINS OPTICAL ACTIVITY (R)-1-(4-FLUORO PHENYL)ETHYLAMINE
Document Type and Number:
Japanese Patent JP2011231071
Kind Code:
A
Abstract:

To provide an industrial optical resolution which obtains optical activity (R)-1-(4-fluoro phenyl)ethylamine.

The optical resolution is carried out using natural type L-(-)-malic acid as a resolving agent, thereby optical activity (R)-1-(4-fluoro phenyl)ethylamine can be obtained. Further, the optical resolution is combined with an optical resolution which uses natural type L-(+)-tartaric acid for a resolving agent to obtain optical activity (S)-1-(4-fluoro phenyl)ethylamine, thereby a resolution efficiency of optical activity (R)-1-(4-fluoro phenyl)ethylamine can be improved. Moreover, in the optical resolution, a salt which consists of optical activity (R)-1-(4-fluoro phenyl)ethylamine and natural type L-(-)-malic acid and becomes a key diastereomer salt has been found out as a novel compound.
