36.1% | With sulfuric acid; nitric acid; acetic acid; at 8 - 10℃; for 1.75h; | Example 4; 4-(2-Fluorophenyl)-7-methyl-6-(pyrimidin-5-yloxy)-9H-pyrido[3,4-b]indole-1- carboxamide; l-Bromo-2,5-dimethyl-4-nitrobenzene; To a slurry of 2-bromo-1,4-dimethylbenzene (10.13 g, 54.7 mmol) in acetic acid (44 mL) at 8 C (inner temperature) was added a solution of nitric acid (6 mL, 134 mmol) in sulfuric acid (22 mL, 413 mmol) over 45 min; temperature rose to 10 C. After 1 hr, the reaction mixture was poured into ice and stirred, filtered and washed with water to give a light yellow solid. This was triturated with EtOH (10 mL) to give the desired product (4.550 g, 19.78 mmol, 36.1% yield) as an off-white solid. |
Yield | Reaction Conditions | Operation in experiment |
---|---|---|
149 mg (82%) | With potassium fluoride;palladium diacetate; In tetrahydrofuran; | EXAMPLE 36 Synthesis of 2,5-dimethylbiphenyl An oven dried resealable Schlenk tube was evacuated and backfilled with argon and charged with palladium acetate (2.2 mg, 0.01 mmol, 1.0 mol percent), 2-(di-tert-butylphosphino)biphenyl (6.0 mg, 0.020 mmol, 2.0 mol percent), phenylboronic acid (183 mg. 1.5 mmol), and potassium fluoride (174 mg, 3.0 mmol). The tube was evacuated and backfilled with argon, and THF (1 mL) and 2-bromo-p-xylene (0.138 mL, 1.0 mmol) were added through a rubber septum. The tube was sealed with a teflon screwcap, and the reaction mixture was stirred at room temperature until the starting aryl bromide had been completely consumed as judged by GC analysis. The reaction mixture was then diluted with ether (30 mL), filtered through celite, and concentrated. The crude material was purified by flash chromatography on silica gel to afford 149 mg (82percent) of the title compound. |
