Odparek poskytl po dělení na sloupci silikagelu (slušní činidlo petroléter obsahující až 20 % obj. diethyléteru) 0,31 g (68 %) l-£4-(3-fnethoxy-3-methyl-2-brombutoxy)feny3jpropyleateru.0.2 g (1 mmol) of 3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylic acid, 0.36 g (1.1 mmol) of 1-[4-(3-methoxy-3-methyl-2-bromobutoxy)phenyl]-1-propanol, 0.2 g (1 mmol) of dicyclohexylcarbodiimide and 0.01 g (0.1 mmol) of N,N-diethylaminopyridine were dissolved and stirred in 10 ml of anhydrous diethyl ether at 15 to 20 °C for 2 hours. After diluting the reaction mixture with diethyl ether and filtering, the ether layer was washed successively with 6% aqueous hydrochloric acid and water, dried and evaporated. The residue, after separation on a silica gel column (a suitable reagent is petroleum ether containing up to 20% by volume of diethyl ether), yielded 0.31 g (68%) of 1-[4-(3-methoxy-3-methyl-2-bromobutoxy)phenyl]propyl ether.
