반응 단계
2H-tetrazol-5-amine (1.29 g, 12.5 mmol), 4-(chloromethyl)-3,5-dimethylisoxazole (1.56 mL, 12.5 mmol) and potassium carbonate (1.73 g, 15.5 mmol) in DMF (20 mL) were heated to 80° C. with stirring for 16 hours. The reaction was cooled to room temperature, diluted with dichloromethane (100 mL) and washed consecutively with brine and water. The organics were dried over sodium sulfate and concentrated with rotary evaporation. The crude product was purified by silica gel chromatography (0-10% gradient ethyl acetate/dichloromethane) affording 2-((3,5-dimethylisoxazol-4-yl)methyl)-2H-tetrazol-5-amine as a white crystalline solid (970 mg, 40% yield) MS M+H calculated 195.1, found 195.
