Water → 4-(2-Pyridyl)Benzoic Acid

Participants

Reaction Steps

2-(p-Toluyl)pyridine (17.2 g) was suspended in water (200 ml), and to the suspension potassium permanganate (21.0 g) was added. The mixture was heated under reflux for 18 hours. After the reaction mixture was allowed to cool, and insoluble matter was removed by filtration, dichloromethane was added to the filtrate, and the resultant water layer was separated and acidified with 2N hydrochloric acid. The solution was concentrated, and precipitate was collected by filtration to obtain the title compound (7.07 g) as a white solid.
