*Procedure  

To a stirred solution of ZrCp2Cl2 (0.292 g, 1.0 mmol) in dry THF (5.0 mL) under argon at -80 °C, nBuLi (0.8 mL, 2.5 M solution in hexanes, 2.0 mmol) was added dropwise and stirred for 10 minutes. N-Allyl-N-methyl-N-[(Z)-3-phenyl-2-propenyl]amine (558, 188 mg, 1.0 mmol) as a solution in THF (2.0 mL) was added dropwise, warmed to room temperature stirred for 5 hrs.  After cooling the reaction mixture to –78 °C, benzyl chloride (129 mg, 1.1 mmol) was added followed by LDA (2.0 mmol, 1.0 mL).  The mixture was stirred for 1 hrs before quenching with methanol (5.0 mL) and a saturated solution of NaHCO3 (8.0 mL).  The product was extracted into diethyl ether (3 x 100 mL), the combined organic layer washed with water (4 x 50 mL), brine (50.0 mL), dried over MgSO4, filtered and the solvent removed under reduced pressure.  Column chromatography (SiO2, 0-100 % Et2O:petroleum including 5 % Et3N) afforded the title compound as a viscous colourless oil (181 mg, 0.65 mmol, 65 %).
