Reaction Steps

A mixture of methyl 4-chloropyridine-2-carboxylate (200 mg), 3-fluoro-4-nitrophenol (202 mg) and chlorobenzene (0.6 ml) was stirred under a nitrogen atmosphere at 120° C. for 2 hrs and 20 min. The reaction mixture was cooled down to room temperature to give a solidified reaction mixture, which was then dissolved in a small amount of N,N-dimethylformamide and subjected to silica gel column chromatography (eluent; hexane:ethyl acetate=1:2, ethyl acetate, then ethyl acetate:methanol=20:1 to 10:1). Fractions containing the target compound were concentrated to provide the titled compound (94 mg, 27.5%) as a pale yellow solid.
