Reaction Steps

A reaction mixture of 4-acetyl-5-cyclohexyl-3-hydroxy-1-(4-methylphenyl)-1,5-dihydro-2H-pyrrol-2-one (139 mg, 0.44 mmol) and ammonium formate (342 mg, 4.44 mmol) in ethanol (0.2M, 2.2 ml) is heated at reflux for 16 hours. The solvent is removed in vacuo to give a white residue. Water is added to the residue to dissolve some of the white solid leaving a sandy-coloured precipitate. This mixture is then filtered, washed with a small amount of diethyl ether and dried under high vacuum at room temperature to give a pale brown solid.
