Participants

Reaction Steps

A solution of 2.0 g (7.19 mmoles) of [2-(2-fluorobenzoyl)-4-chlorobenzoic acid], in 40 ml of methanol and 0.3 ml of sulfuric acid was refluxed for 10 hrs and then evaporated. The residue was partitioned between 50 ml of dichloromethane and 30 ml of dilute ammonium hydroxide, and the organic layer was dried and evaporated. The resulting oil was dissolved in 20 ml of dichloromethane, filtered through 25 g of Florisil and eluted with dichloromethane. The solvent was evaporated and the oil was crystallized from ether and recrystallized from dichloromethane/ether/petrol to give white rods: mp 115°-116° C.
