Reaction Steps

To a solution of 10 g (38.3 mmol) of triphenylphosphane in 100 ml of THF were added 6.7 g (3.83 mmol) of DEAD over 5 min at room temperature. After 30 min at room temperature, 5 g (25.5 mmol) of 3-hydroxy-4-methoxybenzoic acid ethyl ester and 4.87 g (25.5 mmol) of 2-(2,4-dichlorophenyl)ethanol were added and the mixture was stirred at room temperature for 12 h. The solvent was removed and the residue was separated by chromatography to give 3.6 g (38%) of the title compound.
