Benzoyl chloride (14.06 grams, 0.1 mole), Aldrich Chemical Co., Inc., Milwaukee, Wisconsin, was slowly added to a mixture of [compound (X)] hexahydro-1H-furo(3,4-c)pyrrole (11.3 grams, 0.1 mole) and sodium hydroxide (10 grams) in 300 ml of water at 10°C. After the addition of benzoyl chloride, the reaction mixture was stirred at room temperature for 2 to 3 hours and the product was extracted with diethyl ether (4 × 200 ml). Removal of the ether gave the product 5-benzoyl-hexahydro-1H-furo(3,4-c)pyrrole, represented by formula (XI), as a clear viscous liquid which solidified on standing. The product was crystallized from diethyl ether and had a melting point of 47° to 48°C.
