81282-60-2, Step 4 3-Ethoxy-4-(2-oxo-2,3-dihydrobenzooxazol-7-ylamino)cyclobut-3-ene-1,2-dione A mixture of 0.247 g of 7-amino-3H-benzooxazol-2-one (1.6 mmol, 1 eq) and 0.36 ml of 3,4-diethoxycyclobut-3-ene-1,2-dione (2.5 mmol, 1.5 eq) in 9 ml of ethanol was stirred at ambient temperature for 2 days (formation of a precipitate). Ethanol was added in order to promote the fall of the precipitate, which was filtered off, washed with diethyl ether and dried under vacuum at 45 C. 0.35 g of product was obtained in the form of a light khaki solid. Yield=78%.
