Reaction Steps

Bis(dibenzylidineacetone)palladium (2 mg, 0.0035 mmol) and (2′-dicyclohexyl phosphanyl-biphenyl-2-yl)-dimethylamine (3.3 mg, 0.0084 mmol) were added to dry toluene (10 mL purged with argon) and stirred for 15 minutes under argon. Potassium tert-butoxide (140 mg, 1.25 mmol), 6-fluoro-1,2,3,4-tetrahydroisoquinoline hydrochloride salt (150 mg, 0.8 mmol) and N-(4-Bromo-2-chloro-6-trifluoromethyl-phenyl)-3-cyclopentyl-propionamide (200 mg, 0.5 mmol) were then added and the reaction mixture was stirred at 90° C. overnight. The reaction mixture was then cooled to room temperature; concentrated, and purified by thin layer chromatography (dichloromethane:methanol 5%) to afford the title compound as a solid.
