Phenylacetyl chloride (15.46 grams, 0.1 mole), Aldrich Chemical Co., Inc., Milwaukee, Wisconsin, was slowly added to a mixture of hexahydro-1H-furo(3,4-c)pyrrole hydrochloride (14.96 grams, 0.1 mole) and 300 ml aqueous sodium hydroxide (10.0 grams, 0.25 mole NaOH in water) at 10°C. After the phenylacetyl chloride addition, the ice bath was removed and the reaction mixture was stirred for 1.5 hours. The reaction mixture was extracted with diethyl ether (4 × 200 ml) and the extract treated with DARCO G-60 (activated carbon). Removal of diethyl ether gave 5-phenylacetyl-hexahydro-1H-furo(3,4-c)pyrrole (19.35 grams) a clear viscous liquid which solidified on cooling. This product was recrystallized from diethyl ether and had a melting point of 47.5° to 48.5°C.
