Bromopinacolone → HCID 20330256, compound

Participants

Reaction Steps

A mixture of 12.96 grams (g) (0.1 mole) of 5-chloro-2-hydroxypyridine, 17.9 g (0.1 mole) of 1-bromo-3,3-dimethyl-2-butanone, and 15 g (0.054 mole) of silver carbonate in hexane was stirred and heated at reflux temperature for 48 hours. The reaction mixture was filtered, and the solvent removed by evaporation. The residue was dissolved in methylene chloride and filtered through silica gel. Evaporation of the solvent gave 10.5 g (46 percent (%) yield) of 1-(5-chloro-2-pyridinyloxy)-3,3-dimethyl-2-butanone. A sample recrystallized from pentane had a melting point of 68°-69.5° C.
