Imidazole → 1-Indanone

Participants

Reaction Steps

To a solution of 4-hydroxy-1-indanone (25.0 g, 169 mmol) and imidazole (28.7 g, 422 mmol) in DMF (500 ml) was added tert-butyldimethylchiorosilane. The reaction mixture was stirred overnight at room temperature and treated with water (500 ml) and extracted with diethyl ether (500 ml). The organic phase was collected and dried over sodium sulfate. Evaporation gave a yellow oil which was distilled under reduced pressure to give indanone (1) (35.44 g, 135 mmol, 79.9%) as a colourless oil (120–121° C./0.1 mbar).
