Versuchsvorschrift
A solution of 11-(2-oxazolin-2-yl)-9,10-dihydro-9,10-ethanoanthracene (4.122 g) in 1.074 N hydrochloric acid (13.9 ml) is allowed to stand at room temperature for 2.5 hours. The reaction mixture is mixed with dioxane to dissolve the precipitate formed and evaporated at room temperature under reduced pressure to remove the solvent. The residue is recrystallized from anhydrous ethanol-ether to give 2-aminoethyl 9,10-dihydro-9,10-ethanoanthracene-11-carboxylate hydrochloride 1/2 hydrate (4.641 g) as crystals melting at 155 to 158° C. IR (Nujol), 3379, 1735 cm-1.
