Reaction Steps

280 μl (3.7 mmol, 10 eq) of trifluoroacetic acid are added to a solution of 184 mg (0.37 mmol, 1 eq) of 4-(2,4-bis(benzyloxy)-5-fluorophenyl)piperidine-1-carboxylic acid tert-butyl ester in 3 ml of dichloromethane. The reaction medium is stirred at ambient temperature for 1 hour. The reaction medium is treated with 10 ml of water and then extracted with dichloromethane. The organic phases are combined, washed with a saturated solution of sodium hydrogen carbonate and then with a saturated solution of sodium chloride, dried over magnesium sulphate and evaporated. 150 mg of 4-(2,4-bis(benzyloxy)-5-fluorophenyl)piperidine are obtained. Yield=100%.
