実験手順

A solution of sodium hydrogen carbonate (10.5 g, 119.8 mmol) in water (125 ml) was added to 2-methyl-1-(2-oxo-2-phenyl-ethyl)-pyridinium bromide (35.0 g, 119.8 mmol) and the reaction heated to reflux for 30 min. The resultant solid was filtered, washed with water and then dried under vacuum to yield 2-phenyl-indolizine (16.0 g, 70%).
