Reaction Steps

2-Amino-4-chloropyridine (2.57 g) was dissolved in dimethylsulfoxide (30 ml), and then 2-chloro-4-nitrophenol (6.94 g) and N,N-diisopropylethylamine (14 ml) were added thereto, followed by stirring at 160° C. for 6 days. The reaction mixture was cooled down to room temperature, and partitioned between ethyl acetate and a 1 N aqueous solution of sodium hydroxide. The organic layer was washed with a 1 N aqueous solution of sodium hydroxide and brine in this order, and dried over anhydrous sodium sulfate. The solvent was evaporated to give a residue, which was purified by silica gel column chromatography (eluent; hexane:ethyl acetate=1:2, then ethyl acetate) to provide the titled compound (574 mg, 11%) as brown powder.
