tert-butyl N-(3-iodophenyl)carbamate

反応条件: temp:25.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A solution of methyl 3-ethynyl-5-nitrobenzoate (1.45 g, 7.08 mmol), tert-butyl (3-iodophenyl)carbamate (2.26 g, 7.08 mmol) in THF (28 mL) was treated with bis(triphenylphosphine)palladium(II) chloride (248 mg, 0.354 mmol), copper(I) iodide (108 mg, 0.566 mmol) and N,N-diisopropylethylamine (2.47 mL, 14.2 mmol) and stirred at 25° C. overnight. The reaction was diluted with water and extracted with ethyl acetate three times. The combined organic solutions were dried with sodium sulfate, filtered, and concentrated in vacuo. The crude residue was purified by flash column chromatography to yield the desired product (1.85 g, 66%). LCMS for C21H20N2O6Na (M+Na)+: m/z=419.3. extracted with ethyl acetate three times The combined organic solutions were dried with sodium sulfate filtered concentrated in vacuo The crude residue was purified by flash column chromatography

実験手順: A solution of 3-ethynylaniline (1.16 g, 9.87 mmol) and tert-butyl (3-iodophenyl)carbamate (3.0 g, 9.4 mmol) in THF (28 mL) was treated with bis(triphenylphosphine)palladium(II) chloride (330 mg, 0.47 mmol), copper(I) iodide (140 mg, 0.75 mmol) and N,N-diisopropylethylamine (3.27 ml, 18.8 mmol), and stirred at 25° C. overnight. The reaction was diluted with water and extracted with ethyl acetate three times. The combined organic solutions were dried with sodium sulfate, filtered, and concentrated in vacuo. The crude residue was purified by flash column chromatography to yield the desired product (1.42 g, 49%).

実験手順: 2-(4-Bromo-benzyl)-4-(2,4-dichloro-phenyl)-1H-imidazole (1 g, 2.6 mmol) was treated with (3-iodo-phenyl)-carbamic acid tert-butyl ester following general procedure R to provide {3-[2-(4-bromo-benzyl)-4-(2,4-dichloro-phenyl)-imidazol-1-yl]-phenyl}-carbamic acid tert-butyl ester. The bromophenyl product (370 mg, 0.64 mmol) was treated as described in general procedure G using 4-ethoxycarbonylphenyl boronic acid to provide 4′-[1-(3-tert-butoxycarbonylamino-phenyl)-4-(2,4-dichloro-phenyl)-1H-imidazol-2-ylmethyl]-biphenyl-4-carboxylic acid ethyl ester.
