Procedure

To a solution of N-{6-[4-(piperazine-1-carbonyl)phenoxy]-pyridin-3-yl}-4-trifluoromethyl-benzamide (430 mg, 0.91 mmol) in methanol was added 1,2-epoxycyclohexane (180 mg, 1.83 mmol), and the resulting solution was stirred for 1 day under reflux. The resulting reaction solution was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (chloroform:methanol=35:1), and then ethyl acetate was added. The precipitated white powder was filtered off and washed with ethyl acetate, to thereby yield 284 mg of the title compound.
