Reaction Steps
A solution of 2.779 g (10 mmol) 2,4′-dibromoacetophenone and 1.152 g (10 mmol) tetrahydro[1,3]oxazolo[2,3-b][1,3]oxazole in 20 ml of dichloromethane was refluxed for 3 hours. The precipitate was filtered off, washed twice with dichloromethane and dried. 3.801 g (96.7%) of white amorphous product was obtained, which can be further purified by recrystallisation from rectified ethanol.
