Trifluoroacetic acid → 3-Methoxyazetidine 2,2,2-trifluoroacetate

Participants

Reaction Steps

To a solution of tert-butyl 3-methoxyazetidine-1-carboxylate (step 1, 110 mg, 0.57 mmol) in dichloromethane (6.0 mL) was added trifluoroacetic acid (6.0 mL). The resulting solution was stirred at room temperature for 4 h. The volatile materials were removed under the reduced pressure to afford 120 mg (quant.) of the title compound as a highly viscous oil:
