Vorschrift

Benzoyl chloride 3.0 g (0.021 mol) and 1.69 g (0.021 mol) pyridine were mixed together under nitrogen and allowed to react at room temperature overnite. Benzaldehyde 2.23 g (0.021 mol) was added and the mixture was allowed to stand at ambient temperature for 4 days. Recrystallization from ethanol:ether gave 4.27 g (0.013 mol), 62%, α-benzoyloxybenzylpyridinium chloride, mp 174.5°-176.5°.
