Reaction Steps
0.012 m of DCC is added to 0.01 m of 4-pentylphenyl 3-chloro-4-hydroxybenzoate (obtainable by esterification of 3-chloro-4-hydroxybenzoic acid with 4-pentylphenyl with the addition of sulfuric acid and boric acid, J. org. Chem. Vol. 40 (1975) 2998), 0.012 m of 2-chloro-3-methylbutyric acid and 100 ml of methylene chloride at room temperature, with stirring. Further working up is carried out analogously to Example 3 to give 4-pentylphenyl 3-chloro-4-(2-chloro-3-methylbutyryloxy)-benzoate (optically active).
