A mixture of the above described 4-methoxy-benzofuran-3-one oxime (6.15 g, 34.3 mmol) in ethanol (500 mL) with 10% palladium on carbon (6.15 g) was hydrogenated at 23° C. and atmospheric pressure for 18 h. Filtered the catalyst off, washed with ethanol, evaporated the filtrate totally and dried in high vacuum to give the title compound as a light yellow oil (3.65 g, 64%); MS: m/e=166.2 (M+H−).
