Synthesis of [14C] labeled 2-methoxypyrimidine-5-carboxylic acid

A versatile method for 14C labeling of 2-methoxypyrimidine-5- carboxylic acid at the 2-position has been developed after encountering difficulties with traditional approaches to label the carboxyl function. The method developed can also be used for 14C labeling other positions of the pyrimidine ring system. Copyright

METHODS AND INTERMEDIATES FOR THE PREPARATION OF OPTIONALLY RADIO-LABELED IMATINIB

The invention relates to new processes for the manufacture of N-{5-[4-(4-methyl-piperazino- methyl)-benzoylamido]-2-methylphenyl}-4-(3-pyridyl)-2-pyrimidine-amine of formula (I), new processes for the manufacture of metabolites of N-{5-[4-(4-methyl-piperazino-methyl)- benzoylamido]-2-methylphenyl}-4-(3-pyridyl)-2-pyrimidine-amine observed after administration of the compound to warm-blooded animals as well as to intermediates used in said processes. New starting materials as well as processes for the preparation thereof are likewise the subject of this invention. The processes described herein are especially suitable to furnish said compounds having isotopic labeling. The such obtained labeled compounds are in particular suitable to track and to investigate into the metabolism of N-{5-[4-(4-methyl- piperazino-methyl)-benzoylamido]-2-methylphenyl}-4-(3-pyridyl)-2-pyrimidine-amine and its pharmaceutically acceptable salts in clinical and pre-clinical studies.
