Reaktionsschritte
Bis(dibenzylidineacetone)palladium (390 mg, 0.68 mmol) and (2′-dicyclohexyl phosphanyl-biphenyl-2-yl)-dimethylamine (800 mg, 2.0 mmol) were added to dry toluene (150 mL purged with argon for 30 minutes) and stirred for 30 minutes under argon. Potassium tert-butoxide (4.75 mg, 42.3 mmol), 6-fluoro-1,2,3,4-tetrahydro-isoquinoline hydrochloride salt (3.2 g, 17.0 mmol), and N-(4-bromo-2,6-dimethyl-phenyl)-3,3-dimethyl-butanamide (5 g, 16.8 mmol) were then added, and the reaction mixture was stirred at 80° C. overnight. The reaction mixture was then cooled to room temperature and recrystallized from toluene to afford the title compound as a solid. (5.11 g, 83%).
