Ethanol → HCID 12789591, compound

Participants

Reaction Steps

To a mixture of 2 ml of water, 2 ml of ethanol and 0.4 g of potassium hydroxide was added 100 mg of (10,11-dihydro-11-oxo dibenzo[b,f]oxepin-2-yl)-acetamide, and the resulting mixture was refluxed with stirring for 5 hours. After cooling, to this was added water, and the mixture was washed with ethyl acetate. The aqueous layer was acidified with hydrochloric acid and extracted with ethyl acetate. The extract was washed with a saturated sodium chloride solution and dried over anhydrous sodium sulfate. The solvent was distilled off to obtain yellow crystals, which were chromatographed over 9 g of silica gel and eluted with chloroform/methanol (50/1), thereby obtaining 77 mg (yield: 77%) of (10,11-dihydro-11-oxo dibenzo-[b,f]oxepin-2-yl)-acetic acid. This acid was recrystallized from acetone/n-hexane to give colorless crystals having a melting point of 155.7°-157° C.
