Bis(dibenzylidineacetone)palladium (390 mg, 0.68 mmol) and (2′-dicyclohexylphosphanyl-biphenyl-2-yl)-dimethylamine (800 mg, 2.0 mmol) were added to dry toluene (150 mL purged with argon) and stirred for 15 minutes under argon. Potassium tert-butoxide (4.75 mg, 42.3 mmol), 6-Trifluoromethyl-1,2,3,4-tetrahydroisoquinoline hydrochloride salt (4.82 g, 20.3 mmol) and N-(4-Bromo-2,6-dimethyl-phenyl)-3,3-dimethyl-butyramide (5 g, 16.8 mmol) were then added and the reaction mixture was stirred at 80° C. over night. The reaction mixture was then cooled to room temperature and recrystallized from toluene to afford the title compound as a solid. (5.55 g, 79%).
