To a solution of tert-butyl 3-(2,4-dichlorophenoxy)azetidine-1-carboxylate (1.2 g, 3.78 mmol) in CH2Cl2 (10 mL) was added trifluoroacetic acid (TFA) (7 mL) and the reaction mixture was stirred at RT for 2 h. The mixture was concentrated under reduced pressure and filtered, washing with chloroform followed by diethyl ether to obtain 3-(2,4-dichlorophenoxy) azetidine (0.800 g, 100%) as a TFA salt.
