反应详情

A 25 mL round-bottom flask was charged with aniline (1 mL, 8.77 mmol), hexane-2,5-dione (4 mL, 43.86 mmol) and AcOH (5 mL). The reaction mixture was refluxed for 4 hrs. The mixture was diluted with HCl (10%) and extracted with EtOAc. The organic layer was dried over Na2SO4 and the solvent was removed under reduced pressure to give 190 mg of compound 4 (75%). MS [M++1]=172, LC-MS: tR=2.54 min.
