Reaction Conditions

Reaction Steps

A mixture of 3-[(4-methoxyphenyl)amino]-4-nitrobenzohydrazide (1.60 g, 5.29 mmol), 3-(3-fluorophenyl)propionic acid (0.89 g, 5.29 mmol) and phosphorus oxychloride (5.29 mL) was stirred at 100° C. for 2 hr. The reaction mixture was cooled to 0° C., neutralized with saturated aqueous sodium hydrogen carbonate solution, and extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated. The residue was purified by basic silica gel column chromatography (hexane/ethyl acetate=3/1) to give the title compound (1.51 g, yield 69%) as orange crystals.
