Reaction Steps

9 g of the 2-dipropylamino-6-methoxy-7-nitro-1,2,3,4-tetrahydronaphthalene obtained in accordance with Example 1(b) are introduced into 200 ml of ethanol, together with 1 g of Raney nickel. At ambient temperature, hydrogenation is carried out under pressure until the absorption has stopped. After evaporation of the solvent, an oil remains which is shown to oxidise fairly readily in air.
