실험 절차

To a solution of 4-(4-formyl-2-thiazolyl)-1-[[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl]piperidine (i.e. the product of Example 2, Step B) (0.8 g, 2.07 mmol) in tert-butanol (5 mL) was added N1-methyl-1-phenyl-1,2-ethanediamine (43.57 mg, 0.29 mmol). The reaction mixture was stirred at room temperature under a nitrogen atmosphere for 30 minutes, and then potassium carbonate (107.8 mg, 0.78 mmol) and iodine (43.57 mg, 0.33 mmol) were added. The reaction mixture was stirred at 70° C. for 3 h and then quenched by addition of saturated aqueous sodium sulfite solution until the iodine color almost disappeared. The reaction mixture was extracted with chloroform, and the organic layer was washed with saturated aqueous sodium bicarbonate solution and brine, dried (Na2SO4), filtered and concentrated. The residue was purified by preparative thin-layer chromatography on silica gel using a mixture of 94% ethyl acetate, 5% methanol and 1% triethylamine as eluant to give 64 mg of the title product, a compound of the present invention, as an oil.
