YieldReaction ConditionsOperation in experiment
With sulfuric acid; In acetic acid; The diethyl glutamate used as starting material was obtained as follows:- A mixture of <strong>[320-47-8]4-nitro-2-trifluoromethylbenzonitrile</strong> (J.Amer.Chem.Soc. 1954, 76 , 1051; 5.6 g), glacial acetic acid (20 ml) and sulphuric acid (concentrated, 30 ml) was stirred and heated to 130C for 45 minutes. The mixture was cooled, poured onto ice (100 ml) and extracted with ethyl acetate (3 x 150 ml). The combined extracts were washed with aqueous 0.05N-hydrochloric acid solution, dried over sodium sulphate, filtered and evaporated. The residue was purified by chromatography on a silica gel column using ethyl acetate as eluent. There was thus obtained 4-nitro-2-trifluoromethylbenzamide (5.16 g), m.p. 192C.
