Carbonate Ion → 3-[2-(trifluoromethyl)-4'-fluorobenzhydryloxy]-N-(tert-butyl)azetidine-1-carboxamide

Participants

Reaction Steps

To a solution of 3-[2-(trifluoromethyl)-4′-fluorobenzhydryloxy]azetidine hydrochloride (162) (200 mg, 0.55 mmol) in anhydrous DCM (5 mL) was added MP-carbonate (3.01 mmol/g; 550 mg, 1.65 mmol) and tert-butyl isocyanate (65 μL, 0.55 mmol). The resultant mixture was shaken at ambient temperature for 16 h, after which time it was poured onto a DCM-wetted SCX-2 (1 g) cartridge. The sample was eluted with DCM (16 mL), then evaporated to afford the desired product as a colourless glass (204 mg, 87%).
