Place lithium hexamethyldisilazane (12 mL of a IM solution in tetrahydrofuran, 12 mmol) under an argon atmosphere and cool to 0° C. Add trimethylsilylacetylene (1.7 mL, 12 mmol) and stir for 1 hour at 0° C. Add benzaldehyde (1.06 g, 10 mmol) in tetrahydrofuran (25 mL). Allow to warm to room temperature and stir for 3 hours. Pour the mixture into ethyl ether and water, separate the organic phase and evaporate the solvent in vacuo. Filter the oil through silica gel (20% ethyl acetate/hexane) and evaporate the solvent in vacuo to yield the title compound.
