This document discusses properties, synthesis, and reactions of pyridine. It describes that pyridine is more basic than pyrrole. Common synthesis methods include the Hantzsch pyridine synthesis, Guareschi Synthesis, from 1,5-dicarbonyl compounds, and from oxazoles. Pyridine undergoes electrophilic addition and substitution reactions at its carbon atoms. It also undergoes nucleophilic substitution preferentially at the 2-position. Pyridine can act as a nucleophilic catalyst and undergo reduction. The document briefly mentions medicinal uses of pyridine.
