Phthalimide → 2-(3-(phenylthio)propyl)-1H-isoindole-1,3(2H)-dione

Participants

Reaction Steps

Diethyl azodicarboxylate (14 ml, 89 mmol) was added over 3 minutes to a stirred solution of 3-phenylthiopropanol (14.91 g, 89 mmol), triphenylphosphine (23.25 g, 89 mmol) and phthalimide (13.05 g, 89 mmol) in tetrahydrofuran (350 ml) at room temperature. After 15 hours, the mixture was concentrated in vacuo. Flash chromatography of the residue, eluting with 1:1 ether/hexane, gave the title compound as a white solid (22.5 g 85%). NMR (200 MHz, CDCl3): δ 2.0 (q, 2H), 2.95 (t, 2H), 3.85 (t, 2H), 7.25 (m, 5H), 7.8 (m, 4H).
