5-溴-2-乙基异吲哚炔-1-酮

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of methyl 4-bromo-2-(bromomethyl)benzoate (0.5 g, 2 mmol) (AstaTech Cat. No. 27012), ethylamine in THF (1.0 mL, 2.0 M) (Aldrich Cat. No. 395072), and potassium carbonate (0.34 g, 2.4 mmol) in ethanol (5 mL) in a sealed vial was stirred at 40° C. overnight. The solid was filtered off. The filtrate was concentrated under reduced pressure. The residue was purified by flash chromatography on a silica gel column with ethyl acetate in hexanes (0-50%) to afford the desired product (0.28 g). LCMS (M+H)+=240.0/242.0. The solid was filtered off The filtrate was concentrated under reduced pressure The residue was purified by flash chromatography on a silica gel column with ethyl acetate in hexanes (0-50%)
