実験手順

The solution of 50 g of 2-cyanomethyl-6-methoxy-1-tetralone in 1000 ml of ethanol is hydrogenated in the presence of 15 g of Raney nickel at atmospheric pressure and room temperature until 2 mole equivalents of hydrogen are consumed. The mixture is filtered, the filtrate evaporated and the crude product dissolved in 500 ml of N hydrochloric acid. The solution is washed with diethyl ether, treated with charcoal, filtered and the filtrate is basified with 3 N aqueous sodium hydroxide. It is extracted with methylene chloride, the extract dried, evaporated, the residue crystallized from petroleum ether and recrystallized from hexane, to yield the 7-methoxy-3,3a,4,5-tetrahydro-2H-benz[g]indole melting at 102°-104°.
