Participants

Reaction Steps

To a stirring solution of methyl 3-(2,3-dimethoxy-6-(1-oxo-1,3-dihydroisobenzofuran-5-yl)phenoxy)-2,2-dimethylpropanoate (200 mg, 0.49 mmol) in tetrahydrofuran (15 mL) was added lithium hydroxide (102.5 mg, 2.45 mmol) in water (5 mL) and the resultant reaction mixture was stirred at RT for 4 h. The reaction mixture was concentrated under reduced pressure, the residue was acidified using 1N HCl solution to pH 5 and then extracted with ethyl acetate (3×). The combined ethyl acetate layers were washed with brine, dried over anhydrous sodium sulphate and concentrated under reduced pressure to afford the title compound as a solid (120 mg, 63%).
