Procedure

A solution of 2-nitro 5-phenyl phenol (1.2 g, 5.5 mmol) in methanol was treated with 10% Pd/C (1.2 g). The reaction mixture was flushed with hydrogen and allowed to stir overnight. The reaction mixture was filtered through celite and the filtrate was concentrated in vacuo to afford desired (1.01 g, 98%). EI-MS m/z 186 (M+H)+
