Reaction Steps
A mixture of 1-Boc-3-methylsulfonyloxymethyl-azetidine (1.47 g), 3-nitro-5-trifluoromethyl-phenol (1.15 g) and K2CO3 (1.15 g) in DMF (20 ml) at 80° C. was stirred overnight. The reaction was cooled to RT and diluted with 25 mL of sat. NaHCO3 and 50 mL of EtOAc. The organic phase was separated and washed with brine (25 mL), dried over Na2SO4 and concentrated in vacuo. The crude compound was purified by column chromatography (50% EtOAc/hex).
