YieldReaction ConditionsOperation in experiment
29.4% In acetic anhydride; ethyl acetate; EXAMPLE 18 Preparation of 5-Nitro-<strong>[51310-54-4]2-(trifluoromethyl)indole</strong> STR35 A solution of <strong>[51310-54-4]2-(trifluoromethyl)indole</strong> (0.2 g, 1.1 mmole) in acetic anhydride is treated with (0.131 g, 0.54 mmole of) Cu(NO3)2.3H2 O at 0 C., stirred for 2.5 hours at room temperature and diluted with water and ether. The phases are separated; the organic phase is washed sequentially with saturated NaHCO3 and brine, dried over MgSO4 and concentrated in vacuo to give a yellow solid residue. The residue is chromatographed (silica gel/20% ethyl acetate in hexanes) to give the title product as a yellow solid, 0.073 g (29.4% yield), mp 190-193 C., identified by IR, 1 H-NMR, 19 FNMR and mass spectral analyses.
8% With copper(II) nitrate trihydrate; acetic anhydride; at 0 - 20℃; for 2.5h; 200 mg (1.0 mmol) of <strong>[51310-54-4]2-trifluoromethylindole</strong> w'as dissolved in 1 mL of acetic anhydride. The mixture w?as cooled to 0 C and 131 mg (0.54 mmol) of Cu(N03)23H?.0 was added. The reaction mixture was stirred at room temperature for 2.5 hours. Water and diethyl ether was added, and the organic phase was extracted three times with 8 % NaHCCh solution and once with water. The organic phase was dried over NaiSCri, and evaporated to dryness. 63 mg of 2-trifluoromethyl-5-nitroindole was obtained.

Over 15 minutes, about 2.4 g of a suspension of sodium hydride at 50% in oil was added in small fractions and 6.5 ml of benzyl bromide in solution in 10 ml of tetrahydrofuran were introduced over 5 minutes. The mixture was stirred for 42 hours at ambient temperature and then was poured into water saturated with monosodium phosphate. The mixture was extracted with ethyl ether, and the extracts were dried and concentrated to dryness by distillation under reduced pressure. The residue was chromatographed over silica and eluted with a mixture of hexane and ethyl acetate (9/1) to obtain 12.54 g of 1-benzyl-<strong>[51310-54-4]2-trifluoromethyl-(1H)-indole</strong> melting at approx. 20 C.

(1983) 48-3233 and 10 ml of tetrahydrofuran were mixed together under an inert atmosphere at +5 C. and after 15 minutes, 2.4 g of sodium hydride in oil were added. After 2 minutes, 4.5 ml of 2-bromo-propyne were introduced and the resulting mixture was stirred for 30 minutes at +5 C., then for one hour at 25 C. Another 4.5 ml of bromo-propyne were added and the mixture was stirred for 4 hours and then poured into an iced solution of monosodium phosphate and extracted with ethyl ether. The extracts were concentrated to dryness by distillation under reduced pressure and the residue was chromatographed over silica and eluted with a mixture of hexane and ethyl acetate (95/5) to obtain 8.88 g of 1-(2-propynyl)-<strong>[51310-54-4]2-trifluoromethyl-(1H)-indole</strong> melting at 59 C.

YieldReaction ConditionsOperation in experiment
With sodium hydrogencarbonate;aluminium trichloride; In nitromethane; dichloromethane; STEP A 2-trifluoromethyl-3-formyl-(1H)-indole 6.1 g of aluminum chloride and 20 ml of methylene chloride were mixed together at -65 C. under an inert atmosphere and a solution of 4.61 g of <strong>[51310-54-4]2-trifluoromethyl-(1H)-indole</strong> (J. Org. Chem., 1974 Vol. 39, p. 1836), 1.4 ml of nitromethane and 20 ml of methylene chloride were added at -60 C. 3.3 ml of dichloromethyl ether in solution in 10 ml of methylene chloride were added to the suspension of the resulting mixture was stirred for 15 minutes at -65 C. The temperature was allowed to rise and at about -10 C., a strong evolution of hydrochloric acid was observed which ceased at about 0 C. The black solution obtained was stirred for 30 minutes at 25 C. and the reaction mixture was poured into water and extracted with methylene chloride. The organic phases were washed with an aqueous solution of sodium bicarbonate, then with water and concentrated to dryness under reduced pressure to obtain 4.6 g of 2-trifluoromethyl-3-formyl-(1H)-indole.
