Procedure

7 g of 2-dipropylamino-6-hydroxy-5-nitro-1,2,3,4-tetrahydronaphthalene hydrobromide are suspended in 250 ml of ethanol and hydrogenation is carried out at ambient temperature, in the presence of 1 g of 5% palladium-on-charcoal, under a pressure of about 0.3 MPa. The solvent is then evaporated off and the residue is triturated in diethyl ether. The product obtained melts at 215°-218° C. (with decomposition).
