Reaction Steps

To MsOH (50 mL) was added methyl 4-((3,5-dihydroxyphenyl)sulfanyl)-3-oxobutanoate (15.1 g) at room temperature. The mixture was stirred at room temperature for 30 min. The mixture was poured into ice-water at 0° C. and extracted with EtOAc. The organic layer was separated, washed successively with water and brine, dried over MgSO4 and concentrated in vacuo. The residue was purified by silica gel column chromatography (EtOAc/hexane). The product was crystallized from EtOAc-IPE to give the title compound (7.20 g).
