A procedure for preparing diphenylamine compounds of the formula **(See formula)** where R represents methyl or ethyl; R1 represents hydrogen, fluorine, chlorine, bromine, iodine, cyano, methyl, nitro or trifluoromethyl: R2 and R5 independently represent hydrogen, fluorine, chlorine, bromine, nitro, methyl or trifluoromethyl, with the proviso that not more than one of R2 and R5 represents nitro; R3 and R4 independently represent hydrogen, methyl, fluorine, chlorine, bromine or trifluoromethyl; with the condition of a) not more than one of R1, R2, R3, R4 and R5 represents methyl, except that R3 and R4 can both represent methyl; b) when r1, R2, R3, R4 or R6 represents methyl or fluorine, two or three of R1, R2 and R5 represent hydrogen, chlorine or bromine; c) not more than one of R1, R2, R3, R4 and represents trifluoromethyl, except that R3 and R4 can both represent trifluoromethyl; d) when R2 or R5 represent trifluoromethyl, R1 represents hydrogen, chlorine or bromine; e) when one and only one of R3 and R4 represents trifluoromethyl, two or three of R1, R2 and R5 represent hydrogen, chlorine or bromine; f) two fluorine atoms are not adjacent to each other; g) when R2 or R5 represents nitro, R1 represents hydrogen, chlorine, bromine or nitro; h) when r1, R2, R3, R4 or R5 represents trifluoromethyl, none of r1, R2, R3, R4 and R5 represents fluorine or methyl; characterized by reacting an erilin compound of the formula: **(See formula)** wherein R1, R2, R3, R4 and R5 are as defined above, and R'' is hydrogen, methyl or ethyl, with a 2-halo-5-nitrobenzotrifluoride compound of formula: **(See formula)** where X is halo; followed by alkylation of the compound thus obtained, where R'' is hydrogen.
