Participants

Reaction Steps

To a solution of 3,5-dichloro-2-fluoro-4-(3-isopropyl-4-hydroxyphenylthio)-6-hydroxycarbonylmethylaminopyridine (25 mg, 0.06 mmol) in CH2Cl2 (1.5 mL) was added 3-chloroperoxy-benzoic acid (11 mg). The mixture was left to stir overnight (ca. 15 h) at ambient room temperature. The product was extracted with EtOAc (25 mL). The organic extract was washed with brine (25 mL), dried (Na2SO4), filtered and concentrated in vacuo. The isolated crude product was purified by preparative HPLC (from 50% B to 100% B for 10 min, Solvent A=90% H2O-10% MeOH-0.1% TFA Solvent B=10% MeOH-90% H2O-0.1% TFA, at 20 mL/min using column YMC ODS S5 20×100 mm) to afford 16.5 mg (64%) of title compound as a white solid.
