Reaction Steps

0.18 g (0.44 mmol) 1-[2-hydroxy-3-(4-octylphenoxy)propyl]indole-5-carbonitrile (Example 15A) is dissolved in 15 ml tert-butanol, mixed with 0.23 g (3.6 mmol) pulverized, 88% potassium hydroxide and heated under reflux for 11 h. Having cooled down, the mixture is hydrolyzed in water and acidified with 1N hydrochloric acid. Three extractions with diethyl ether, concentration to half the volume on the rotary evaporator, washing with water and with saturated NaCl solution, drying on sodium sulfate, filtration and reconcentration on the rotary evaporator leave as a crude product a yellowish solid which is purified on silica gel by means of column chromatography (flow agent: petroleum ether/ethyl acetate 1:1) and yields the product as a solid.
