 | Hazard Information | Back Directory |  | [Description] 
 4-Fluoro-thalidomide is the Thalidomide-based Cereblon ligand used in the recruitment of CRBN protein. It can be connected to the ligand for IRAK4 protein by a linker to form PROTAC IRAK4 degrader-1 (HY-129966).
 |  | [Uses] 
 2-(2,6-Dioxo-3-piperidinyl)-4-fluoro-1H-isoindole-1,3(2H)-dione is an intermediate in the synthesis of N-[2-Aminoethyl] Pomalidomide TFA Salt (A6095150. N-[2-Aminoethyl] Pomalidomide TFA is a thalidomide derivative, a potent inhibitor of TNF-α production. It is an anti-inflammatory and anti-tumor agent used in the treatment of multiple myeloma.
 |  | [Synthesis] 
 A mixture of 4-fluoroisobenzofuran-l,3-dione (498.33 mg, 3.00 mmol), 3- aminopiperidine-2,6-dione hydrogen chloride (493.77 mg, 3.00 mmol) and NaOAc (246.09 mg, 3.00 mmol) in HOAc (10 mL) was stirred at 135 °C overnight, cooled and concentrated in vacuo. The residue was suspended in H2O (100 mL) and stirred at room temperature for 4 hours. The solid was collected via filtration and dried in vacuo to afford 2-(2,6-dioxopiperidin-3-yl)-4-fluoroisoindoline-1,3-dione as a white solid.
