3-[[2-(4-Chlorophenyl)-4-methylthiazol-5-yl]methoxy]piperidine (59.1 mg, 0.183 mmol) and 2-fluorobenzaldehyde (0.0984 mL, 0.915 mmol) were dissolved in dimethylsulfoxide (2 mL). To this solution, cesium carbonate (119 mg, 0.366 mmol) was added and the mixture was stirred at 130° C. for 3 hours. Subsequently, water was added and the mixture was extracted with ethyl acetate and the extracted washed with brine, followed by drying over magnesium sulfate and evaporation of the solvent. Purification of the resulting residue by silica gel column chromatography (hexane:ethyl acetate=20:1->5:1) gave 47.8 mg (61%) of the desired compound as a colorless oil.
