Versuchsvorschrift
A solution of 2,3-dimethylpyrrolo[2,3-b]pyridine (146 mg, 1 mmol) and phenacyl chloride (170 mg, 1.1 mmol) in 3 ml CH3CN was refluxed for 4.5 h. The mixture was allowed to cool and the precipitated product filtered off and washed with a small volume of ice cold CCl4 affording 207 mg (69%) pure title compound as the hydrochloride salt.
