摘要:
N-[2-(4-carboxymethoxyphenyl)-1-(R)-1-methylethyl]-2-(R)-2-hydroxy 2-(3-chlorophenyl)ethanamine or the methyl ester thereof, or a pharmaceutically acceptable salt thereof, ('the RR-isomer') optionally in admixture with N-[2-(4-carboxymethoxyphenyl)-1-(S)-1-methylethyl]-2-(S)-2-hydroxy-2-(3 chlorophenyl)ethanamine, or the methyl ester thereof, or a pharmaceutically acceptable salt thereof, ('the SS-isomer') wherein the SS-isomer forms less than 50% by weight of the mixture of the RR- and SS- isomers; a process for preparing such compounds, pharmaceutical compositions comprising such compounds and the use of such compounds and compositions in medicine and agriculture.
