실험 절차

2′-Chloro-5′-nitro-biphenyl-4-carboxylic acid ethyl ester (1.04 g) in ethanol 30 ml) and 2M HCl (5.0 ml) was hydrogenated at RTP for 3 h. The mixture was then filtered through celite and the solvent evaporated to give the title compound as a dark red solid (1.02 g) which was used in the next stage without further purification.
