実験手順
288 parts of β-naphthol, 3 parts of triphenyl phosphite and 80 parts of methylamine gas are heated for 10 hours under pressure at 200° C in a pressure autoclave. The pressure is 40 atmospheres. When the two-phase mixture has cooled, water is added, the batch is stirred for 30 minutes at 70° C and the lower oily phase is separated off and distilled. 305 parts of N-methyl-β-naphthylamine, boiling at 165° - 166° C/12 mm Hg, are obtained. This corresponds to a yield of 97% of theory.
