Procedure
Thionyl chloride (1.6 ml) was added dropwise to a stirred suspension of 1-(4-pyridyl)piperidine-4-carboxylic acid (2.17 g) in methylene chloride (30 ml) and the mixture was stirred at ambient temperature for 1 hour. The mixture was evaporated to give 1-(4-pyridyl)piperidine-4-carbonyl chloride which was used without further purification.
Workup
- customThe mixture was evaporated
