Article abstract of DOI:10.1016/S0040-4039(99)01053-9

The lithium salts of 2-, 3- and 4-pyridinecarboxylic acids undergo deprotonation at the position adjacent to the carboxylate group when treated with LTMP in THF at 0 °C, -50 °C and -25 °C, respectively. The lithiation conditions could be extended to chlor
