PURPOSE: A process for preparing the titled compound by reacting alkyl halide compounds with aromatic compounds using a catalyst in the presence of a solvent is provided which produces alkyl aromatic compounds useful as intermediates or final products of various industrial chemicals. CONSTITUTION: An aryl aromatic compound of formula (III) is prepared by alkylating aryl halides of formula (I) and aromatic compounds of formula (II) using a catalyst selected from metal indium alone, indium and a solid base, indium and a base and a 4A molecular sieve in the presence of a solvent or in its absence. In formula, R1 and R2 denote each H or straight or side chained C1 to C5 hydrocarbon substituted to carbon of the aryl group selected from methyl, ethyl, propyl, butyl and pentyl; X denotes Cl, Br, I or F; R3 and R4 denote each H, methyl, F, hydroxyl or methyl. The aryl halides of formula (I) and aromatic compounds of formula (II) are used in a molar ratio of 100 : 1 to 1 : 100.
