Reaktionsschritte
200 parts 2-mercaptonicotinic acid, 970 parts of water, 215 parts of 50% NaOH, and 164 parts of benzyl chloride were combined and the resulting solution was refluxed for 2 hours. After dilution with 2580 parts of water, the solution was acidified with 207 parts of 36% HCl. The resulting slurry was cooled and filtered. The wet cake was washed with water and dried to give 307 parts (97.1%) of 2-(phenylmethylthio)-3-pyridinecarboxylic acid, m.p. 190°-193° C.
