4-Methyl-1-piperidin-1-ylpentan-1-one (372.4 g) and toluene (1000 mL) were mixed. To the mixture was added (Ph3P)IrCl(CO) (633 mg). In a water-bath, 1,1,3,3-tetramethyldisiloxane (627 mL) was added dropwise to the mixture. The resulting mixture was stirred at RT for 2 hr. The reaction mixture was concentrated in vacuo to give the title compound (844 g) as a crude product.
