Using a procedure analogous to that described in Example 3, 5.85 gm (67% of theory) of the ester of the formula ##EQU28## having a boiling point of 181°-185°C at 0.05 mm Hg were obtained by refluxing a mixture consisting of 6.11 gm (0.025 mol) of 3-(2-fluoro-4-biphenylyl)-1-butanol, 6.20 gm (0.051 mol) of benzoic acid, 0.5 gm of p-toluene-sulfonic acid and 40 ml of toluene until no more water separated out.
