With potassium phosphate; tetrakis(triphenylphosphine) palladium(0); In 1,4-dioxane; water; at 95℃;Inert atmosphere; | Compound number 301 was prepared as follows. To a solution of <strong>[335349-57-0]5-chloro-4-iodo-2-nitroaniline</strong> (6 g, 20.1 mmol) in dioxane (100 ml) and water (10 ml) which was purged and maintained with an inert atmosphere of nitrogen was added[2,4-bis(trifluoromethyl)phenyl]boronic acid (10.3 g, 40.01 mmol), K3PO4 (8.6 g, 40.70 mmol) and Pd(pph3)4 (2.3 g, 2.04 mmol) at room temperature. The resulting solution was stirred overnight at 95 C. in an oil bath. The resulting mixture was concentrated under vacuum to give a residue, which was purified by a silica gel column, eluting with 2% to 3% ethyl acetate in petroleum ether to produce 4-[2,4-bis(trifluoromethyl)phenyl]-5-chloro-2-nitroaniline as a crude light yellow solid (2.2 g, crude). Next, to a solution of 4-[2,4-bis(trifluoro-methyl)phenyl]-5-chloro-2-nitroaniline (2.2 g, crude) in ethanol (50 ml) was added hydrogen chloride (conc, 1.5 ml) and Zn powder (2.2 g, 33.85 mmol). The resulting solution was stirred for 2 h at 90 C. in an oil bath. The reaction was then quenched by the addition of water (300 ml), adjusted pH to 8 with aqueous sodium carbonate and then extracted with ethyl acetate (3×100 ml). The combined organic layers were washed with brine (200 ml), dried and concentrated under vacuum to produce 4-[2,4-bis(trifluoromethyl) phenyl]-5-chlorobenzene-1,2-diamine as a crude brown solid (1.75 g, crude). Finally, a Solution of 4-[2,4-bis(trifluoromethyl)phenyl]-5-chlorobenzene-1,2-diamine (300 mg, crude) in trifluoroacetic acid (10 ml) and hydrogen chloride (conc, 2 ml) was stirred overnight at 80 C. in an oil bath. The solution was evaporated and dissolved in water (30 ml), adjusted to pH 8 with aqueous sodium carbonate and extracted with ethyl acetate (3×50 ml). The combined organic layers were dried over anhydrous sodium sulfate and concentrated under vacuum to give a residue, which was purified by a silica gel column with 10% ethyl acetate in petroleum ether to produce 6-[2,4-bis(trifluoromethyl)phenyl]-5-chloro-2-(trifluoromethyl)-1H-1,3-benzodiazole as a off-white solid (132.4 mg). |
