Then the tube was stirred at room temperature under air for the indicated time until complete consumption of starting material as monitored by TLC analysis. After the reaction was finished, the reaction mixture was extracted with ethyl acetate (3 20 mL). The combined extracts were washed with aqueous NaHCO3, dried over anhydrous Na2SO4 and evaporated in a rotary evaporator under reduced pressure. The crude product was purified by filtration through a column chromatography on silica gel employing ethyl acetate-hexane mixture to afford the desired product. The purity of the compound was confirmed by NMR and mass analysis, vide infra.

To this mixture add drop-wise 20 g. of 90% nitric acid with stirring. Stir at about 5 C. for 2 hours and pour into about 11/2 liters of ice and water with stirring. Collect the 3'-trifluoromethyl-4'-nitro-isobutyranilide by filtration and wash with water until substantially free of excess acid.
41 g With sulfuric acid; nitric acid; at 0 - 5℃; for 3h; Flutamide was synthesised and purified by modification of a literature procedure.4 3-Trifluoromethylisobutyranilide (58 g, 0.25 mol) was dissolved in concentrated sulfuric acid (200 mL, 2.2 mol) at 0-5 C with efficient agitation (CAUTION: strong acid). A pre-cooled mixture of 98% sulfuric acid (20 mL, 0.22 mol) and 65% nitric acid (20 mL, 0.29 mol) (CAUTION: strong acids) was added dropwise to the above solution while the temperature was controlled at 0-5 C. Stirring was continued for 3 h, and the mixture was poured onto crushed ice (500 g) mixed efficiently with a mechanical stirrer in a 2 L beaker. The crude product was filtered under suction. The precipitate obtained was dissolved in 96% ethanol (350 mL) under reflux and decolourised with charcoal (10 g) by 15 minutes heating and filtered. The filtrate was cooled and precipitated with drop-wise addition of distilled water (1.5 L). After 60 min in an ice-cooled bath the yellow precipitate was filtered off and dried in a good ventilating hood. The impure product (50 g, 0.18 mol) was twice re-crystallised from toluene (150 mL) for further purification. The pale yellow needles haped crystals (41 g, 0.15 mol) of flutamide were obtained after gentle drying under reduced pressure (60% based on the starting material, 3-trifluoroisobutyranilde). The overall yield of three steps was 45% based on benzotrifluoride. M.p. 111.5-112 C (lit.4,1 111.5-112 C and110-111 C).

95% With sodium sulfite; for 16h;Reflux; General procedure: A mixture of aromatic nitro compound (10 mmol), sodium sulfite (35 mmol) and carboxylic acid (80 mmol) wasrefluxed for 16 hours. The reaction mixture was poured to a mixture of ethyl acetate (50 mL) and water (50 mL). Organicphase was separated, dried on sodium sulfate and evaporated to produce crude product. The product was purified bycolumn chromatography or by re-crystallization in the mixture of methanol : water (1:1). Furthermore, it is important tonote that this methodology is scaled-up to kilogram scale without any difficulty.
