Versuchsvorschrift

To a mixture of 3,4,4a,9a-tetrahydro-1H-benzo[4,5]furo[2,3-c]pyridine hydrochloride (3.2 g, 15.1 mmol) and sodium hydrogenocarbonate (14 g) in chloroform (40 mL), was slowly added a solution of acetyl chloride (1.5 mL, 21 mmol) in chloroform (5 mL). After stirring for 2 h another portion of acetyl chloride was added. After 5 h the solvent was evaporated. Purification using silica gel chromatography (78 g SiO2) eluting with ethyl acetate yielded 1-(3,4,4a,9a-tetrahydro-1H-benzo[4,5]furo[2,3-c]pyridin-2-yl)-ethanone.
