Participants

Reaction Steps

This compound was produced by modifications of the methods used J. Med. Chem., 1991, 34, 1071 starting with N-hydroxyphthalimide (10.0 g, 61.3 mmol), 1,3-dibromo-propane (24.8 g, 123 mmol) and triethylamine (12.4 g, 123 mmol). The crude material was purified by flash chromatography through silica gel using chloroform to give 2-(3-bromo-propoxy)-isoindole-1,3-dione (9.30 g, 53%) as a white powder. 1H NMR (400 MHz, CDCl3); δ 7.81 (m, 2H), 7.73 (m, 2H), 4.34 (t, 2H), 3.68 (t, 2H), 2.28 (m, 2H).
