Versuchsvorschrift

Combine (6-bromo-phthalazin-1-yl)-(4-tert-butyl-phenyl)-amine (60 mg, 0.19 mmol), 2-(trifluoromethyl)phenyl-boronic acid (50 mg, 0.26 mmol) in 1,2-dimethoxyethane (10 mL) and bubble nitrogen into the mixture for 10 minutes. Add tetrakis(triphenylphosphine)palladium(0) (12 mg, 0.01 mmol) and 2M Na2CO3 (1 mL) and heat at 80 C. for 48 hours. Let the mixture cool to room temperature, dilute with water (10 mL), and extract twice with EtOAc (10 mL each). Dry (Na2SO4), evaporate, and purify on a preparative silica gel plate (2000 micron) eluting with 75% hexane-EtOAc to provide (4-tert-butyl-phenyl)-[6-(2-trifluoromethyl-phenyl)-phthalazin-1-yl]-amine as a straw colored solid. Mass Spec. 421.2.
