Water → 1-(2,4-Bis-benzyloxy-5-bromo-phenyl)-ethanone

Participants

Reaction Steps

51.2 g of 1-(2,4-Bis-benzyloxy-phenyl)-ethanone (0.154 mol, 1 eq) were dissolved in 250 ml DMF. 27.42 g N-bromosuccinimide (0.154 mol, 1 eq) in 100 ml DMF were added dropwise. The mixture was stirred at room temperature over night. The reaction mixture was poured onto 700 ml of water and the precipitate filtered off. The filter cake was rinsed with water and the colourless solid was recrystallised from 370 ml acetonitrile.
