The resolution of 5-methyltetrahydrofolic acid |
| abstract |
Described is a method of preparing (6S)-5-methyl-tetrahydrofolic acid by separation of the racemic mixture, (6R,S)-5-me-thyl-tetrahydrofolic acid, using a based characterized in that N-ethyl-Z-aminomethylpyrrolidine or one of its optical isomers is used as the base. |
