The solution is stirred under nitrogen for 2 hours and then heated under reflux for 5 hours. The solvent is removed in vacuo and the residue is treated with 200 ml of anhydrous ether. The ether solution is washed, dried, and concentrated in vacuo to give about 6.8 g of yellow solid. This is recrystallized from hexane to give the name product, mp about 97°-98°.
