HCID 221510N-Butylnaphthalen-1-amineYield 87%

Procedure

288 parts of α-naphthol, 10 parts of triphenyl phosphite and 160 parts of n-butylamine are heated for 20 hours at 220° C in a pressure autoclave, whilst stirring. The further working up is carried out as described in Example 3. 346 parts of n-butyl-α-naphthylamine, boiling at 160° - 162° C/18 mm Hg, are obtained, corresponding to a yield of 87% of theory.
