実験手順

500 mg (1.46 mmol) of 4-(6-bromopyridin-2-yl)piperazine-1-carboxylic acid tert-butyl ester, 460 mg (1.61 mmol) of 2-(5,5-dimethyl-5,6,7,8-tetrahydronaphthalen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane and 620 mg (2.92 mmol) of tripotassium phosphate trihydrate are suspended in 10 ml of ethylene glycol monomethyl ether, degassed a number of times, and 82 mg (0.04 mmol) of bis(triphenylphosphine)palladium(II) dichloride are added under nitrogen atmosphere. The reaction mixture is treated in an ultrasound bath for 10 min, subsequently irradiated in the microwave at 100° C. for 90 min, 50 ml of water and 50 ml of ethyl acetate are added, and the mixture is filtered. The residue is discarded. The organic phase of the filtrate is separated off, and the aqueous phase is extracted three times with ethyl acetate. The combined organic phases are dried over Na2SO4 and evaporated. The crude product is purified by means of flash chromatography on silica gel.
