Versuchsvorschrift
288 parts of α-naphthol, 10 parts of triphenyl phosphite and 100 parts of ethylamine gas are heated for 20 hours at 240° C, whilst stirring. After the mixture has cooled, it is next stirred for 20 minutes at 70° C with 1,000 parts of 2.5 percent strength by weight aqueous sodium hydroxide solution. The organic phase is separated off, washed with 2,000 parts of water at 30° C, again separated off and distilled. 308 parts of N-ethyl-α-naphthylamine boiling at 119° - 120° C/0.1 mm Hg are obtained, corresponding to a yield of 90% of theory.
