Procedure

A mixture of methyl 4-(3-fluorobenzyl)benzoate (0.574 g; 2.35 mmol) and lithium hydroxide (0.493 g; 11.75 mmol) in water (6 mL) and THF (6 mL) was heated at 60° C. for 3 hours and concentrated under reduced pressure. The resulting aqueous solution was acidified with a 6N solution of hydrochloric acid in water. The resulting precipitate was filtered off to give 0.541 g (quantitative) of 4-(3-fluorobenzyl)benzoic acid which was used without further purification.

Workup

  1. concentrationconcentrated under reduced pressure
  2. filtrationThe resulting precipitate was filtered off
