Versuchsvorschrift
1-(4-Chloro-2-pyridyl)ethanone (440 mg, 2.83 mmol) and ethyleneglycol (480 mg, 3 mmol) were mixed with toluene (10 ml), a catalytic amount of p-toluenesulfonic acid was added and the mixture was heated at reflux overnight. The mixture was evaporated to dryness to yield 523 mg of a solid (2.6 mmol, 93%). MS (APCI) m/z=200.0 [M+H]+.
