참여 물질

반응 단계

To a solution of NaBH4 (60 mg, 1.58 mmol) in MeOH (3.0 mL) at room temperature was added ethyl[4-(6-bromopyridin-2-yl)-1H-1,2,3-triazol-1-yl]acetate (245 mg, 0.79 mmol) in MeOH (7.0 mL) The reaction was stirred at room temperature for 2 h. It was then diluted with water and extracted with EtOAc (2×). The combined organic layers were washed with brine, dried (MgSO4), filtered, and evaporated. Flash chromatography (20-100% EtOAc/hexanes) afforded the title compound as a colorless gum.
