4-Benzoyl-1-(3-fluoro-4-methoxyphenyl)pyrrolidin-2-one → 4-Benzoyl-1-(3-fluoro-4-hydroxyphenyl)pyrrolidin-2-one

Participants

Reaction Steps

A mixture of 4-benzoyl-1-(3-fluoro-4-methoxyphenyl)pyrrolidin-2-one (Step 2, 1.0 g, 3.2 mmol) in 20 mL of 1 M BBr3/CH2Cl2 was stirred at RT for 16 h. The solution was concentrated in vacuo and the residue was diluted with 50 mL of MeOH and concentrated in vacuo again. The resulting white solid was washed with 50% EtOAc/hexane to give the title compound. MS (ESI pos. ion) m/z: 300.4 (M+H). Calc'd Exact Mass for C17H14FNO3: 299.3.
