Participants

Reaction Steps

To a cooled (−78° C.) solution of 2-Methoxy-4′-(2-nitrophenylamino)-benzophenone (Compound 215, 0.35 g, 1 mmol) in methylene chloride (10 ml), under argon, was added boron tribromide (0.1 ml, 1 mmol) under stirring. The reaction mixture was allowed to come to room temperature. After stirring for 3 h , the reaction mixture was poured into saturated sodium bicarbonate (50 ml) before being extracted with ethyl acetate (2×50 ml). The organic phase was dried (MgSO4), filtered and evaporated to afford the title compound.
