반응 단계
ethyl 6-({2-[(5-nitro(2-pyridyl))amino]ethyl}amino)-2-phenylpyridine-3-carboxylate was prepared from ethyl 3-oxo-3-phenylpropanoate as the starting material and DDQ in the oxidation step. The final product is achieved directly from the chloropyridine by reacting ethyl 6-chloro-2-phenylpyridine-3-carboxylate with 2-(2-aminoethylamine)-5-nitropyridine in CH3CN and Hüing's base at 80° C. for 18 hours. The procedures are analogous to the general method for {2-[(6-amino-5-nitro(2-pyridyl))amino]ethyl}[6-(2,4-dichlorophenyl)-5-imidazolyl(2-pyridyl)]amine.
