Reaction Steps

To a solution of 1.68 g of t-butyl diethylphosphonoacetate in 5 mL of THF was added 400 mg of sodium hydride (60% dispersion in mineral oil) at 0° C. The reaction was warmed to rt and stirred at rt for 20 min. To the resulting solution was added a solution of 1.05 g of 1-benzyl-4-piperidone in 5 mL of THF. The solution was refluxed for 3 h and cooled to rt. After quenching with aqueous NH4Cl, the aqueous phase was extracted with EtOAc (3×). The combined organic phases were dried over MgSO4 and concentrated to give 1.05 g of the title compound as a oil, which was used for the next step without further purification.
