Reaction Conditions

Reaction Steps

1.05 g of 4-(diphenylmethoxy)piperidine was dissolved in 10 ml of N,N-dimethylformamide; 0.57 ml of 4-bromobutyl acetate and 652 mg of potassium carbonate were added, followed by stirring at 50° C. for 3 hours. Ice water was added, followed by extraction with ethyl ether; the extract was washed with saline and dried with magnesium sulfate. After the dry product was concentrated under reduced pressure, the residue was dissolved in 15 ml of ethanol; 8 ml of a 1 N aqueous solution of sodium hydroxide was added, followed by stirring at room temperature. After the mixture was concentrated under reduced pressure, the residue was neutralized with 1 N hydrochloric acid, followed by extraction with ethyl acetate; the extract was washed with saline and dried with magnesium sulfate. After the dry product was concentrated under reduced pressure, the crystal precipitate was collected, washed with ethyl ether and dried to yield 1.21 g of the title compound.
