Procedure

In a 25 ml round-bottomed flask, 1 g of 3-(2,4-bis(benzyloxy)phenyl)azetidine-1-carboxylic acid tert-butyl ester is dissolved in 10 ml of dichloromethane and then 2.5 ml of trifluoroacetic acid are added. The reaction mixture is stirred for 2 hours. The solvents are evaporated off and the residue is then taken up in isopropyl ether. 0.92 g of 3-(2,4-bis(benzyloxy)phenyl)azetidine trifluoroacetate is obtained. Yield=90%.
