Participants

Reaction Steps

To a solution of ethyl 4-[1-[4-[1-[4-(1-acetoxy-2-methylpropyl)-2-fluorophenyl]pentyloxy]benzoyl]indolizin-yl]butyrate (300 mg) in ethanol (3 ml) and 1,4-dioxane (3 ml) was added 1N aqueous solution of sodium hydroxide (1.5 ml). The mixture was stirred at room temperature for 1 hour, and then poured into a mixture of ethyl acetate and 0.5N hydrochloric acid. The organic layer was separated, washed with water and brine, dried over magnesium sulfate and concentrated. The residue was chromatographed on silica gel column eluting with a mixture of chloroform and methanol (25:1) to give 4-[1-[4-[1-[2-fluoro-4-(1-hydroxyl-2-methylpropyl)phenyl]-pentyloxy]benzoyl]indolizin-3-yl]butyric acid (151 mg) as powder.
