Reaction Steps

1 g (2.78 mmol) of 4-oxo-4-(pyrene-1-yl)-butyric acid was dissolved in 30 ml diethylene glycol and 0.5 9 (10 mmol) of hydrazine hydrate as well as 0.56 g (10 mmol) of KOH added thereto. The reaction solution was heated under reflux for 2 hours and then poured onto iced hydrochloric acid (25%), forming a yellow precipitate. Filtration of the solid and recrystallization from EtOH yielded 570 mg (71%) of 4-(pyrene-1-yl)-butyric acid.
