FIELD: organic chemistry. ^ SUBSTANCE: invention relates to method for production of derivatives of general formula , wherein R is C2H5, C3H7, C4H9. Claimed method includes reaction of aniline with aliphatic aldehydes of general formula RCH2CHO, wherein R is as defined above in presence of catalyst. Method is characterized in that as catalyst crystallohydrate of lanthanide trichloride (LnCl3.6H2O, Ln = Pr, Nd, Eu) is used. Process is carried out in C6H5NH2:RCH2CHO:LnCl3.6H2O molar ratio of 45:100:1.2, in air, under atmospheric pressure and room temperature in ethanol for 25 min. Quinoline and derivatives thereof are useful in synthesis of cyan dyes, as extractants, sorbents and corrosion inhibitors. ^ EFFECT: simplified method with increased yield. ^ 1 cl, 1 tbl, 7 ex |
