Acetic Anhydride → HCID 23135820, compound

Participants

Reaction Steps

Acetic anhydride (580 μL, 6.2 mmol) was dropwise added to a pyridine (20 ml) solution of 2-(6′-phenyl-2,2′-bipyridine-6-yl)phenol (1.0 g, 3.1 mmol) obtained by Example 14, then the mixture was stirred for 24 hours at room temperature. The solvent was distilled off from the reaction mixture, and the residue was purified by silica gel column chromatography and recrystallization, thereby obtaining 1.05 g of 6-(2-acetoxyphenyl)-6′-phenyl-2,2′-bipyridine as yellow crystal. Yield: 93.0%.
