N-BOC-2-甲基-4-碘苯胺

反应条件: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of tert-butyl (4-iodo-2-methylphenyl)carbamate (1.04 g), cyclopropylboronic acid monohydrate (422 mg), palladium(II) acetate (35.1 mg), tricyclohexylphosphine (87.5 mg), tripotassium phosphate monohydrate (2.52 g), toluene (8.7 mL), and water (0.87 mL) was stirred at 100° C. for 15 hours. The reaction mixture was left to cool and then diluted with ethyl acetate and filtered through Celite (registered trademark). The filtrate was washed with brine and dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluting solvent: ethyl acetate-hexane) to obtain the title compound (668 mg). 1H-NMR (CDCl3) δ ppm: 0.55-0.70 (2H, m), 0.80-1.00 (2H, m), 1.51 (9H, s), 1.75-1.90 (1H, m), 2.21 (3H, s), 5.85-6.45 (1H, br), 6.75-7.00 (2H, m), 7.45-7.75 (1H, m). The reaction mixture was left to cool filtered through Celite (registered trademark) The filtrate was washed with brine dried over anhydrous sodium sulfate concentrated under reduced pressure The residue was purified by silica gel column chromatography (eluting solvent: ethyl acetate-hexane)

The reaction mixture was allowed to cool to ambient temperature, diluted with ethyl acetate and filtered through celite (registered trademark). The filtrate was washed with water/saturated saline (1/1, 20 mL), dried over anhydrous sodium sulfate and concentrated under reduced pressure.
