Acetyl chloride → 1-(4-(3-Fluoropyrazin-2-yl)piperidin-1-yl)ethanone

참여 물질

반응 단계

To 2-fluoro-3-(piperidin-4-yl)pyrazine (0.311 g, 1.716 mmol) dissolved in DCM (5 mL) was added triethylamine (0.286 mL, 2.06 mmol), then acetyl chloride, reagent grade (0.134 mL, 1.89 mmol). The reaction mixture was stirred at RT for 1 h then partitioned between DCM and water. The aqueous layer was extracted with DCM (3×) and the combined organic layer was washed with brine, dried (Na2SO4) and concentrated to give 1-(4-(3-fluoropyrazin-2-yl)piperidin-1-yl)ethanone as a yellow oil. MS (ESI, pos. ion) m/z: 224.0 (M-56).
