Sodium Hydroxide → 4-(3-(2,6-Dimethylbenzyloxy)phenyl)butyric acid

Participants

Reaction Steps

A solution of Ethyl 4-(3-(2,6-dimethylbenzyloxy)phenyl)butanoate (Step B, 3.26 g, 10 mmol) in abs ethanol (60 ml) was treated with 1N NaOH (20 ml) at room temperature. The reaction mixture was stirred for 3 hours, or until all the starting material is gone, concentrated and diluted with chloroform and acidified by 1M HCl to bring the pH to 3.5-4. The organic layer was washed with brine, dried over Na2SO4, filtered, concentrated and purified by flash chromatography on a silica gel column (chloroform:methanol, 95:5 spiked with acetic acid) to give the title compound as white solid.
