実験手順

A mixture of (1R)-1-[2-(3-methylphenyl)-2H-tetrazol-5-yl]ethanol (251 mg, 1.23 mmol), 2-[4-methyl-5-(methylsulfonyl)-4H-1,2,4-triazol-3-yl]pyrimidine (239 mg, 1.00 mmol) and cesium carbonate (911 mg, 2.80 mmol) in N,N-dimethylformamide (10 mL) was stirred at 65° C. for 15 h. After cooling to room temperature, the product was partitioned between ethyl acetate (300 mL) and water (50 mL). The organic layer was washed with water (3×50 mL) and brine (50 mL), and dried over sodium sulfate. The solvent was concentrated in vacuo. Flash chromatography (silica gel, 2-3% methanol in dichloromethane) yielded the title compound (265 mg, 73%, oil).
