Procedure
Potassium carbonate (1.02 g) and 4-[4-(4-trifluoromethoxybenzyloxy)benzyl]piperidine were added to an N,N-dimethylformamide solution (10 ml) of 2-chlorobenzothiazol-6-ol (1.37 g) and the mixture was stirred at 80° C. for 2 days. After being cooled to room temperature, the mixture was concentrated under reduced pressure. Water was added to the residue, followed by extraction with ethyl acetate. The organic layer was washed with water and a saturated sodium chloride aqueous solution, dried over sodium sulfate, and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=4:1→2:1) to afford the title compound as a white powder (2.1 g).
