A mixture of 1-(1,2,3,5,6,7-hexahydro-s-indacen-4-yl)-ethanone (33 grams), ethanol (250 mL) hydroxylamine hydrochloride (58.5 grams) and pyridine (80 mL) was heated to reflux for a period of 12 hours. The mixture was then cooled to room temperature and concentrated in vacuo. The residue was then treated with 500 mL of water and extracted with chloroform-methanol. The organic phase was dried over anhydrous sodium sulfate and concentrated in vacuo to afford 32 grams of the title compound as a mixture of E and Z isomers, 178.6-182.3° C.
