Reaction Steps
To a solution of 42.59 g (0.11 mole) of diethyl [4-azidobutyl][3-(3-pyridyl)-propyl]-malonate in 270 mL THF and 3.1 mL water is added 29 g (0.11 mole) of triphenyl phosphine and the solution is stirred well for 48 hours. Solvent is evaporated and the residue subjected to flash chromatography to give diethyl [4-aminobutyl][3-(3-pyridyl)- propyl]malonate as an oil.
