Propionyl chloride → HCID 178458828, compound

Participants

Reaction Steps

Stannic chloride (12.0 g) was added dropwise to a mixture of 3-hydroxy-5-(naphth-1-yl)cyclohex-2-en-1-one (10 g) and propionyl chloride (4.25 g) in 1,2-dichloroethane (50 ml). the mixture was stirred and heated at reflux under nitrogen for 6 hr. After cooling, the mixture was poured onto ice. The dichloromethane extract was evaporated and the residue was heated at reflux with a 2M sodium hydroxide solution (20 ml) for 2 hr. After cooling, the solution was poured into an ice/hydrochloric acid mixture. The dried (Na2SO4) dichloromethane extract was concentrated and the residue was purified by column chromatography over silica gel with dichloromethane elution to give 3-hydroxy-5-(naphth-1-yl)-2-propionylcyclohex-2-en-1-one as a white solid.
