Iodine → HCID 71254909, compound

Participants

Reaction Steps

Triethylamine (64 mL, 0.46 mmol)) was added to a solution of triphenylphosphine (60 mg, 0.23 mmol) and iodine (58 mg, 0.23 mmol) in dry DCM (0.5 mL) and stirred for 5 min. Then a solution of ethyl 3-(4-fluorophenyl)-3-oxo-2-(2,2,2-trifluoroacetamido)propanoate (37 mg, 12 mmol) in dry DCM (0.7 mL) was added and the reaction mixture was stirred for 1 hr. The solvent was removed under reduced pressure, and the residue was purified by SiO2 chromatography on silica gel (isocratic DCM) to yield a white solid (31 mg, 88% yield). 1HNMR (400 MHz, CDCl3): d 8.12 (m, 2H), 7.18 (t, 2H, J=8.8 Hz), 4.43 (q, 2H, J=7.2 Hz), 1.39 (t, 3H, J=7.2 Hz). 19FNMR (400 MHz, CDCl3): d −66.10, −107.21. MS (ESI): m/z MS (ESI): m/z 303.9 [M+H]+
