Reaction Steps

In a mixture of 4 mL of a 25% aqueous solution of potassium hydroxide and 5 mL of ethylene glycol was dissolved 350 mg (0.66 mmol) of methyl 4-(4-hydroxy-4-(2-(2-acetoxyethoxy)phenyl)piperidino)-2,2-diphenylbutyrate. The resulting solution was stirred at 130° C. for 2 hours. Water was added to the reaction mixture, followed by neutralization with hydrochloric acid under ice cooling. The crystals thus precipitated were collected by filtration and dried, whereby 230 mg (yield: 73.4%) of 4-(4-hydroxy-4-(2-(2-hydroxyethoxy)phenyl)piperidino)-2,2-diphenylbutyric acid was obtained.
