Phthalimide → (S)-2-(2-(4-Fluorophenyl)propyl)isoindoline-1,3-dione

Participants

Reaction Steps

To a solution of (S)-2-(4-fluorophenyl)propan-1-ol (824 mg, 5.35 mmol, 1.0 equiv), phthalimide (0.824 g, 5.6 mmol, 1.05 equiv), and triphenyl phosphine (2.11 g, 8.03 mmol, 1.5 equiv) in dry THF (18 mL) was added dropwise diethyl azadicarboxylate (DEAD) (3.65 mL, 15% in toluene, 8.03 mmol, 1.5 equiv). The reaction mixture was stirred over 72 h and then concentrated in vacuo. Purification by silica gel chromatography (15-25% EtOAc/Hexanes) provided the title compound (0.9 g, 59%) which was characterized by 1H NMR.
