Procedure

A solution of 0.3 g of 7-nitro-3H-benzooxazol-2-one (1.67 mmol) in 5 ml of ethanol was degassed and then 0.03 g (10% by weight) of palladium on carbon (5%-50% wet) was added thereto. The reaction medium was stirred under a hydrogen atmosphere for 2 hours at ambient temperature. The reaction medium was filtered through celite and concentrated to dryness. 0.25 g of product was obtained in the form of a colorless oil. Yield=99%.
