Reaction Steps

A suspension of the dihydroxyphthalimide from e) (350 mg) in diphenyldichloromethane (4 g) was heated at 160° C. for 3 hours. The resultant solution was cooled and washed with petroleum ether (3×10 ml). The petrol phase separated to give a brown oil which was collected and triturated under diethyl ether (5 ml) to give as a chestnut brown solid, diphenylmethylenedioxyphthalimide (300 mg); NMR (DMSO-d6) 7.5(m,12H); 11.05(s,1H). Cooling of the petrol phase afforded a second fraction of the phthalimide (250 mg).
