Reaction Steps

Bis(dibenzylideneacetone)palladium (2.8 mg) and (2′-dicyclohexylphosphanyl-biphenyl-2-yl)-dimethyl-amine (3.8 mg) were mixed in dry toluene (2.5 mL) under argon for 5 minutes. To this mixture were added sodium tert-butoxide (6 mg), azacycloheptane (7.5 mg) and N-(4-bromo-2,6-dimethyl-phenyl)-2-cyclopentyl-acetamide (1p, 15 mg) and the reaction was heated to 110° C. in a sealed 4 mL vial under argon for 48 hours. The reaction mixture was concentrated in vacuo, sodium hydroxide (2 M, 1.5 mL) was added and the product was extracted with isopropyl acetate (3×1.5 mL). The combined organic phases were dried over magnesium sulfate, concentrated in vacuo and purified by flash chromatography to furnish 7.9 mg (50% yield) of the title compound as an oil. LC-MS-TOF (m/z) 329 (MH+); tR=2.08, (UV, ELSD) 90%, 99%.
