Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Phosphorus oxychloride | HCID 24813 | — |
| Reactant | (1-Oxido-2-pyridinyl)(phenyl)methanone | HCID 849885 | — |
| Product | (6-Chloro-2-pyridinyl)phenylmethanone | HCID 14023163 | — |
Reaction Steps
1.5 g 2-benzoyl-pyridine N-oxide (T. Kato et. al., see reference in Ex. 11) and 3.6 ml POCl3 are refluxed for 25 minutes. The cooled mixture is added to slightly alkaline ice:water, extracted with chloroform, the organic extract dried and solvent removed in vacuo. Yield: 1.1 g of title product, which by thin layer and gas chromatography is identical with that described in Ex. 7.
