3-甲基异喹啉氮氧化物

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

实验步骤: 3-Methyisoquinoline oxide (3.60 g, 22.6 mmol) and acetic anhydride (38 mL) are heated at reflux for 6 hr. After cooling the volatiles are removed and the residue is distilled at 220° C. under 0.5 mbar using a Kugelrohr distillation apparatus to afford 3-methyl-2H-isoquinolin-1-one (900 mg, 27% yield). LC/MS: MS m/e=160 (M+H); RT 2.45 min. at reflux for 6 hr After cooling the volatiles are removed the residue is distilled at 220° C. under 0.5 mbar a Kugelrohr distillation apparatus
