Procedure
2.61 g (11.4 mol) of methyl 4-(bromomethyl)benzoate (IV) synthesized in the 4th step and 3.0 g (11.45 mmol) of triphenylphosphine were dissolved in 100 ml of benzene, and the temperature was raised to the reflux temperature under stirring, at which temperature, the reaction was carried out for 2 hours.
Workup
- temperaturethe temperature was raised to the reflux temperature
