Preparation and uses of Cyclopentanecarboxylic acid,1-phenyl-,2-[2-(diethylamino)ethoxy]ethyl ester: it can be prepared by tetrahydrofuran. The reaction is as follows: (1)Add tetrahydrofuran into hydrobromic acid at first, then add sulfuric acid into the mixture. Via a series of cooling, separation and neutralization you can get 1,4-dibromobutane; (2)1,4-Dibromobutane react with cyanobenzyl to give 1-phenyl-1-cyanocyclopentane; (3)Add water and sulfuric acid into 1-phenyl-1-cyanocyclopentane. After the reaction, you can obtain 1-phenylcyclopentanecarboxylic acid; (4) Add 1-phenylcyclopentanecarboxylic acid into anhydrous trichloroethene. Then add phosphorus trichloride into the mixture with stirring. You can get 1-phenylcyclopentaneformyl chloride through this reaction; (5) 1-phenylcyclopentaneformyl chloride can react with diethylaminoethoxyethanol to give the desired product by esterification. In addition, it can be used as non-narcotic central antitussive.
