3-(benzyloxy)-6-(2-(4-fluorophenyl)-3-(methylcarbamoyl)-6-(N-methylmethylsulfonamido)benzofuran-5-yl)picolinic acid (110 mg, 0.18 mmol) was suspended in THF (2 ml), cooled to 0° C., then 4-methylmorpholine (55.3 mg, 0.55 mmol) and ethylchloroformate (27.7 mg, 0.26 mmol) were added. The resulting mixture was stirred at 0° C. for 1 h, then (R)-1-(4-fluorophenyl)ethylamine was added. The reaction was warmed to RT and stirred for 1 h, then concentrated in vacuo. The resulting residue was purified using column chromatography (eluted with 0-5% MeOH/DCM) to provide (R)-3-(benzyloxy)-6-(2-(4-fluorophenyl)-3-(methylcarbamoyl)-6-(N-methylmethylsulfonamido)benzofuran-5-yl)-N-(1-(4-fluorophenyl)ethyl)picolinamide (100 mg, yield: 76%). MS (M+H)+: 724.
