Reaction Conditions

Reaction Steps

To a suspension of 3-chloro-4-(piperidin-4-yloxy)nitrobenzene (3.00 g) obtained in reference example 8 in pyridine (30 ml) was added 2-bromopyridine (1.25 ml) at room temperature, and the resulting mixture was stirred at 150° C. for 16 hours. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate, and the organic layer was washed with a saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate and evaporated in vacuo. The residue obtained was purified by chromatography on a silica gel column using a mixed solvent of ethyl acetate and hexane (1:2) as the eluent to afford the title compound (0.80 g, yield: 20%) as a yellow solid.
