Trifluoroacetic acid → 3-Azetidinol, 3-acetate, 2,2,2-trifluoroacetate (1:1)

Participants

Reaction Steps

To a solution of tert-butyl 3-acetoxyazetidine-1-carboxylate (Intermediate 95, 0.914 g) in DCM (5 mL) was added TFA (5 mL) and the mixture was stirred at room temperature for 30 minutes. The resultant mixture was concentrated in vacuo and azeotroped with toluene and diethyl ether to give acetic acid azetidin-3-yl ester trifluoroacetate salt (1.40 g) as a clear oil.
