Participants

Reaction Steps

To the solution of 4-[1-(4-bromo-3-[1,3]dioxan-2-yl-phenoxy)-3-methyl-butyl]-benzoic acid methyl ester (1000 mg) in methanol (20 mL) is added sodium hydroxide (5 N aqueous, 2 mL) and stirred for 4 h. The reaction mixture is concentrated and acidified by 5 N HCl (2 mL), extracted with ethyl acetate. Combined organic layers are washed with water and brine, dried over sodium sulfate. Concentration gives the title compound (940 mg) as a white solid.
