Procedure

A solution containing 4.46 g of 1,2-dimethyl-4,5-dibenzoylcyclohexene (Preparation 1) and 8.81 g of ammonium formate in 70 ml of anhydrous ethanol is heated at reflux for 24 hours. A precipitate is obtained which is filtered off and then dissolved in dichloromethane. The organic phase is washed with water, dried over calcium sulphate and concentrated to allow the isolation of 4 g of the expected product.
