Reaction Steps

A 15 mL resealable Schlenk tube was charged with CuI (9.6 mg, 0.0504 mmol, 5.0 mol %), benzamide (145 mg, 1.20 mmol), K3PO4 (430 mg, 2.03 mmol), evacuated and backfilled with argon. trans-N,N-Dimethyl-1,2-cyclohexanediamine (16 μL, 0.102 mmol, 10 mol %), trans-1-iodo-1-hexene (143 μL, 1.00 mmol), and toluene (1.0 mL) were added under argon. The Schlenk tube was sealed with a Teflon valve and the reaction mixture was stirred at 25° C. for 24 h. The resulting light blue suspension was allowed to reach room temperature and then filtered through a 0.5×1 cm pad of silica gel eluting with 10 mL of ethyl acetate. The filtrate was concentrated, the residue was dissolved in 5 mL of dichloromethane and purified by flash chromatography on silica gel (2×15 cm, hexane-ethyl acetate, 15 mL fractions). Fractions 12-19 provided 140 mg (69% yield) of the desired product as white needles.
