N-(2-bromo-3-fluorophenyl)-2,2,2-trifluoroacetamide

Conditions: temp:25.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 4-chloro-2-ethynyl-1-methoxybenzene (255 mg, 1.5 mmol), N-(2-bromo-3-fluorophenyl)-2,2,2-trifluoroacetamide (400 mg, 1.4 mmol), Pd(PPh3)2Cl2 (30 mg, 0.04 mmol) was stirred in TBAF.3H2O (1.43 g, 7 mmol) at 110° C. for 12 hours. The reaction mixture was cooled to 25° C. and added to water, then extracted with ethyl acetate and washed with brine, dried over Na2SO4. After concentrated, the crude product of 2-(5-chloro-2-methoxyphenyl)-4-fluoro-1H-indole (100 mg, yield: 20%) was obtained. MS (M+H)+: 276/278. extracted with ethyl acetate washed with brine dried over Na2SO4 After concentrated
