Versuchsvorschrift

To a solution of m-phenoxybenzyl alcohol (1.89 g) and pyridine (1 ml) in methylene chloride (6 ml) is added a methylene chloride (7 ml) solution of α-isopropyl-4-trifluoromethoxyphenylacetyl chloride, prepared from the corresponding acid (2.46 g) as illustrated in Example 15. After stirring the reaction mixture overnight, it is washed with water, diluted hydrochloric acid solution, dilute potassium hydroxide solution, water and evaporated to an orange oil. Purification by silica gel chromatography gives the desired ester (2.76 g).
