实验步骤: 2.25 g (0.01 mol) of 7-bromo-2-methyl-1-indanone (2), 1.74 g (0.011 mol) of 3,5-difluorophenylboronic acid and 2.33 g (0.022 mol) of sodium carbonate were placed in 38 ml of dimethoxyethane and 12 ml of water in the reaction vessel, the mixture was degassed a number of times and saturated with argon. 45 mg (0.2 mmol) of palladium acetate and 0.1 g (0.4 mmol) of triphenylphosphine (TPP) were added and the reaction mixture was stirred for 2 hours at 80° C. After addition of 50 ml of water, the mixture was extracted 3 times with 30 ml each time of diethyl ether, the ether phase was washed twice with water and dried over magnesium sulfate. Removal of the solvent gave 2.4 g of 2-methyl-7-(3,5-difluorophenyl)-1-indanone as solid. 12 ml of water in the reaction vessel, the mixture was degassed a number of times the mixture was extracted 3 times with 30 ml each time of diethyl ether the ether phase was washed twice with water dried over magnesium sulfate Removal of the solvent

反应条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Using a method similar to Example 22, 8.0 g (0.032 mol) of (2), 5.85 g (0.038 mol) of 4-dimethylaminophenylboronic acid and 7.4 g (0.07 mol) of sodium carbonate were placed in 122 ml of dimethoxyethane and 37 ml of water in the reaction vessel, the mixture was degassed a number of times and saturated with argon. 142 mg (0.6 mmol) of palladium acetate and 385 mg (1.3 mmol) of tris(o-tolylphenyl)phosphine were added and the reaction mixture was stirred for 4 hours at 80° C. After addition of 150 ml of water, the mixture was extracted 4 times with 100 ml each time of diethyl ether, the ether phase was washed twice with 50 ml each time of water and dried over magnesium sulfate. Removal of the solvent and column filtration through neutral aluminum oxide (dichloromethane) gave 6.5 g of 2-methyl-7-(4-dimethylaminophenyl)-1-indanone as an oil. 37 ml of water in the reaction vessel, the mixture was degassed a number of times the mixture was extracted 4 times with 100 ml each time of diethyl ether the ether phase was washed twice with 50 ml each time of water dried over magnesium sulfate Removal of the solvent and column filtration through neutral aluminum oxide (dichloromethane)

实验步骤: 16.9 g (75 mmol) of (2) and 20 g (90 mmol) of 2-trimethylstannylpyridine were placed in 165 ml of tetrahydrofuran in the reaction vessel, the mixture was degassed a number of times and saturated with argon. 350 mg (0.37 mmol) of trans-di(μ-acetato)bis-[o-(di-o-tolylphosphino)benzyl]dipalladium (II) were added and the reaction mixture was refluxed for 24 hours. After addition of 200 ml of water, the mixture was extracted 4 times with 150 ml each time of diethyl ether, the ether phase was washed with 100 ml of water and 100 ml of saturated sodium chloride solution and dried over magnesium sulfate. Removal of the solvent and drying for 24 hours at 0.1 mbar at 60° C. (removal of the trimethylstannyl bromide) gave 15.07 g of (24) as an oil. the mixture was degassed a number of times the reaction mixture was refluxed for 24 hours the mixture was extracted 4 times with 150 ml each time of diethyl ether the ether phase was washed with 100 ml of water and 100 ml of saturated sodium chloride solution dried over magnesium sulfate Removal of the solvent drying for 24 hours at 0.1 mbar at 60° C.
