Abstract
This invention relates to a novel process for preparing 2-halogeno-nicotinic acids. The compounds, especially 2-chloro-nicotinic acid, are intermediates in the preparation of anilino nicotinic acid derivatives. The latter compounds are useful as analgesic anti-diarrheal and anti-inflammatory agents.
