実験手順

A solution of 2-{4-[2-(3,4-dichloro-phenyl)-ethyl]phenylamino}-5-nitrobenzoic acid methyl ester (340 mg, 0.76 mmol) and 1N NaOH (aq.) (4.0 mL) in EtOH (4.0 mL) and THF (4.0 mL) was heated to reflux for 16 hours. The solvent was removed in vacuum. The residue was diluted with H2O and acidified with concentrated HCl to pH 1. The mixture was then extracted with methylene chloride, dried (Na2SO4), filtered and concentrated in vacuo to yield a yellow solid, 329 mg (0.76 mmol, 100%) of the desired product mp 214-217° C.
