Lithium hydroxide (43 mg) was added to methyl 2-Methoxy-5-(thiophene-2-yl)benzoate (102 mg) in a solvent mixture of tetrahydrofuran/methanol/water (2/1/1, 3 ml), and they were stirred overnight. The solvent was evaporated, and the residue was added to 3 N hydrochloric acid. The white solid thus precipitated was taken by the filtration as the title compound.
