A solution of 3-(4′,5′-difluoro-2′-methoxy-biphenyl-4-yloxymethyl)-phenylamine hydrochloride (101 mg, 0.269 mmol), triethylamine (38 uL, 0.269 mmol) and methanesulfonyl chloride (27 uL, 0.349 mmol) in dry pyridine (4 mL) was reacted similar to N-[3-(2′,4′,5′-trifluoro-biphenyl-4-yloxymethyl)-phenyl]-methanesulfonamide above. The crude product was purified by flash chromatography with a 0-15% gradient of ethyl acetate in hexanes to yield 60 mg of N-[3-(4′,5′-difluoro-2′-methoxy-biphenyl-4-yloxymethyl)-phenyl]-methanesulfonamide as a white solid. LC-MS (ES) calculated for C21H19F2NO4S, 419.45; found m/z 418 [M−H]−.
