Procedure

A solution of 1.20 g (3.6 mmol) of 2-(1-ethoxy-carbonyl-piperidin-4-yl)amino-8-methoxy-1,2,3,4-tetrahydronaphthalene in 10 ml of ether was added dropwise at room temperature to the suspension of 0.27 g (7.2 mmol) of lithium aluminum hydride in 10 ml of ether. After stirring &for 15 hours at room temperature, the mixture was diluted with 30 ml of ether. 0.3 ml of water, 0.25 ml of 20% strength sodium hydroxide solution and 1 ml of water were subsequently carefully added dropwise. For drying, 3 g of potassium carbonate were added, and the mixture was stirred for 20 minutes. By filtration and concentration (finally high vacuum), U.90 g (91%) of the title compound was obtained as an oil.
