A solution of 3-(2′,4′,5′-trifluoro-biphenyl-4-yloxymethyl)-phenylamine hydrochloride (76 mg, 0.209 mmol), triethylamine (29 uL, 0.209 mmol) and methanesulfonyl chloride (19.3 uL, 0.249 mmol) in dry pyridine (3 mL) was stirred at ice bath temperature for 1 hr and then at RT for 2 hrs. The reaction mixture was evaporated, re-evaporated from toluene, dissolved in EtOAc, washed with H2O, dried over MgSO4, filtered and concentrated. The crude product was purified by flash chromatography with a 0-25% gradient of ethyl acetate in hexanes and lyophilized to yield 48 mg of N-[3-(2′,4′,5′-trifluoro-biphenyl-4-yloxymethyl)-phenyl]-methanesulfonamide as a white amorphous powder. LC-MS (ES) calculated for C20H16F3NO3S, 407.41; found m/z 406 [M−H]−.
