Ring-alkylated aniline derivs. prodn. - by isomerisation of N-alkyl-aniline derivs., on zeolite catalyst

摘要

Ring-alkylated anilines of formula (I) are obtd. by contacting N-alkylanilines of formula (II) with an acidic zeolite catalyst in the presence of H2 and/or an inert gas at 300-450 deg.C, 20-100 bar and 0.1-1.5 LHSV (where R1 = 1-4C alkyl; R2 = H or 1-4C alkyl).
