Versuchsvorschrift
7.43 g (26.4 mmol) of phenylmethyl 1,2,3,4-tetrahydronaphthalene-2-carbamate were added in portions to a suspension of 4.5 g (26.4 mmol) of lithium aluminium hydride in 200 ml of tetrahydrofuran, and the mixture was heated to reflux for 3 h 30, allowed to cool, and hydrolysed with an excess of aqueous 1N sodium hydroxide solution, the mixture was filtered and concentrated, and the residue was distilled at about 80 Pa between 140 and 240° C. 4.78 g of impure oil were obtained, which was utilised in its impure state in the following step.
