실험 절차

A solution of 460 mg (0.80 mmol) of methyl 4-[(4E)-3-(4-cyanobenzyl)-5-{2-[4-(4-fluorophenoxy)butoxy]phenyl}pent-4-en-1-yl]benzoate in 15 ml of 1-propanol and 2 ml of water is mixed with 1340 mg (23.89 mmol) of potassium hydroxide and stirred at 110° C. for 12 h. After cooling, the mixture is acidified with 1 M hydrochloric acid, and the crystals which have separated out are filtered off with suction, washed several times with water and dried. 325 mg (0.52 mmol, 65% of theory, purity 93%) of the title compound are obtained.
