実験手順

Bis(dibenzylidineacetone)palladium (2 mg, 0.0035 mmol) and 2′-dicyclohexylphosphanyl-biphenyl-2-yl)-dimethylamine (3.3 mg, 0.0084 mmol) were added to dry toluene (5 mL purged with argon) and stirred for 15 minutes under argon. Potassium tert-butoxide (188 mg, 1.7 mmol), 6-chloro-1,2,3,4-tetrahydro isoquinoline hydrochloride salt (165 mg, 0.8 mmol), and N-(4-bromo-2,6-dimethylphenyl)-3,3-dimethylbutanamide (200 mg, 0.67 mmol) were then added, and the reaction mixture was stirred at 80° C. overnight. The reaction mixture was then cooled to room temperature and filtered through silica gel. Purification by preparative thin layer chromatography afforded the title compound as a solid.
