The nitro-p-cresotinic acid used in the experiment has probably nitro group in the ortho position to OH as during nitration of the cresotinic acid (kostanecki and Niementoski Ber. [...] The p-toluenesulphonyl compound of the ester of nitro-p-crestinic acid is formed in presence of diethylaniline; it does not react with ammonia but unlike the corresponding compounds with dinitrcarvacrol and dinitrothymol it gives diphenylamine derivative when boiled with aniline. [...] The excess of aniline was then removed by means of dilute HC1 and the residue was crystallised from alcohol in yellowish needles m. p. 136°. [...] It was also shown that the presence of a CH3 group in the meta position with respect to OH acts unfavourably on the replaceability of the OH group. [...] The colour of the solution gradually changed from dark orange to light yellow as the reaction proceeded to completion and the disodium salt of the codensation product was deposited in crystalline flakes at the bottom of the reaction vessel.
