2-Di-n-propylamino-8-(t-butoxycarbonylacetyl)-1,2,3,4-tetrahydronaphthalene (prepared as in Example 6) (1.0 g, 3.3 mmol) was taken up in 25 ml methanol. Ten equivalents of hydroxylamine hydrochloride (8.3 g, 33 mmol) were added and the reaction stirred at room temperature for 48 hours. The solution was filtered to remove unused hydroxylamine hydrochloride. The mixture was then concentrated and three crystallizations were performed from methanol/ethylacetate. The title compound (30 mg) was recovered.
