Yield	Reaction Conditions	Operation in experiment
44%	Stage #1: at -40℃; for 2 h; Stage #2: With ammonium chloride In tetrahydrofuran; dihydrogen peroxide	To a solution of 4-bromo-1-chloro-2-nitro-benzene (14 g, 0.059 mol) in 400 mL THF at - 40 °C was added dropwise vinylmagnesium bromide (177 mL of 1.0M solution in THF, 0.177 mol). The reaction mixture was stirred for 2 hrs at -40 °C. Aqueous NH₄CI was added and the mixture extracted with ether. The organic phase was dried over Na₂S0_4> concentrated and the residue purified by silica gel column chromatography to give the title compound (6 g, 44 percent). ¹H NMR CDCI₃400 MHz δ 8.5 (s, 1 H), 7.31-7.29 (m, 1 H), 7.26-7.22 (m, 1 H),7.07-7.05 (m, 1 H), 6.65-6.63 (m,1 H).
44%	at -40 - 40℃; for 2 h;	To a solution of 4-bromo-1-chloro-2-nitro-benzene (14 g, 0.059 mol) in 400 mL THF at -40° C. was added dropwise vinylmagnesium bromide (177 mL of 1.0M solution in THF, 0.177 mol). The reaction mixture was stirred for 2 hrs at 40° C. Aqueous NH₄Cl was added and the mixture extracted with ether. The organic phase was dried over Na₂SO₄, concentrated and the residue purified by silica gel column chromatography to give the title compound (6 g, 44percent). ¹H NMR CDCl₃400 MHz δ 8.5 (s, 1H), 7.31-7.29 (m, 1H), 7.26-7.22 (m, 1H), 7.07-7.05 (m, 1H), 6.65-6.63 (m, 1H).
32%	at -40℃; for 1 h; Inert atmosphere	Under a nitrogen gas, 4-bromo-1-chloro-2-nitrobenzene (25g, 0.107mol) dissolved inTHF (250mL) and then - 40 degree celcius added vinylmagnesium bromide (1M in THF, 321mL, 0.321mol) slowly dropwise, and then stirred at -40 degree celcius for 1 hour. Since, NH₄After completion of the reaction with Cl aqueous solution was raised to room temperature.Then, the organic layer was extracted with ethyl acetate, MgSO₄to remove moisture in the organic layer, filtered and concentrated and purified by column chromatography to give 4-bromo-7-chloro-1H-indole (7.89g,Yield: 32percent) It was obtained.
