摘要: The invention relates to a process for obtaining L-dihydroorotic acid by chromatography on an anionic exchange material in a base water mixture under a pressure from about 1.1 MPa to about 40 MPa. The process can be used to investigate the in vitro and in vivo activity of N-(4-trifluoromethylphenyl)-5-methylisoxazole-4-carboxamide, N-(4-trifluoromethylphenyl)-2-cyano-3-hydroxycrontonamide and similar compounds.
