Procedure

Tris(dibenzylideneacetone)dipalladium (0.10 g, 0.00011 mol) and tri-tert-butylphosphonium tetrafluoroborate (0.064 g, 0.00022 mol) in a flask was evacuated and refilled with N2 (3 times). Then 1,4-dioxane (7.0 mL) was added followed by consecutive addition of tert-butyl (3-bromophenyl)carbamate (2.00 g, 0.00735 mol), 2-propen-1-ol (0.854 g, 0.0147 mol), N-cyclohexyl-N-methyl-cyclohexanamine (1.7 g, 0.0088 mol). The reaction mixture was stirred at 40° C. overnight, filtered, and washed with dichloromethane. The filtrate was concentrated and purified by chromatography on silica gel with 40% EtOAc in hexanes to afford the desired product (0.5 g, 30%).
