Versuchsvorschrift

Acetic anhydride (0.437 mL, 4.62 mmol) was added at 0° C. to a solution of 5-methyl-azepan-4-one hydrochloride (0.740 g, 3.08 mmol) in DCM (20 mL) and pyridine (0.25 mL, 3.08 mmol). The reaction mixture was stirred at RT for 8 hours before being partitioned between DCM and H2O. The organic layer was dried (Na2SO4), filtered, and evaporated. The crude residue was purified by SiO2 chromatography (100% EtOAc) to give 0.220 g of 1-acetyl-5-methyl-azepan-4-one (42% yield).
