Abstract

A process for producing 4-alkyl-2-haloanilin compound of the following formula (1), comprising the step of reacting the 2-haloaniline derivative of the following formula (2) with an alkylating agent in the presence of an acid catalyst in an organic solvent or sulfuric acid to introduce group R1, which represents branched chain C3 - C10 alkyl or optionally substituted C3 - C10 cycloalkyl, into the 4-position of the derivative, thereby preparing the compound of formula (1) wherein R1 represents branched chain C3 - C10 alkyl or optionally substituted C3 - C10 cycloalkyl; R2 represents a halogen atom, optionally substituted straight chain or branched chain C1 - C8 alkyl, or optionally substituted C3 - C8 cycloalkyl; R3 represents optionally substituted straight chain or branched chain C1 - C8 alkyl, optionally substituted straight chain or branched chain C2 - C6 alkenyl, or optionally substituted C3 - C8 cycloalkyl; n is an integer of 0 (zero) to 3; and X represents a fluorine and chlorine atom; wherein R2 represents a halogen atom, optionally substituted straight chain or branched chain C1 - C8 alkyl, or optionally substituted C3 - C8 cycloalkyl; R3 represents optionally substituted straight chain or branched chain C1 - C8 alkyl, optionally substituted straight chain or branched chain C2 - C6 alkenyl, or optionally substituted C3 - C8 cycloalkyl; n is an integer of 0 (zero) to 3; and X represents a fluorine and chlorine atom, provided that R is not in the 4-position on the aromatic ring; wherein the acid catalyst is 70 to 90% (w/w) sulfuric acid and the reaction is carried out at a temperature in the range of 60 to 80°C.
