Reaction Conditions

Reaction Steps

Tributylphosphine (3 ml, 0.012 mol) is added to a solution of 2-(2,6-diethyl-4-hydroxy-2,3,6-trimethyl-piperidine-1-yloxy)-propionic acid 3-bromo-propyl ester (4.08 g, 0.01 mol) in acetonitrile (5 ml). The solution is stirred under argon at 60° C. for 23 h. The solvent is evaporated and the residue is triturated with diethyl ether (2×15 ml) to remove the excess of the phosphine. Drying of the oily, in ether insoluble, residue affords 6.45 g of the title compound as a thick resin.
