Procedure
A mixture of methyl 2-phenyl-benzooxazole-6-carboxylate 1u (0.37 g, 1.46 mmol) and LiOH (0.10 g, 4.2 mmol) in THF (4 mL), MeOH (4 mL), and H2O (4 mL) was stirred at room temperature for 6 h. Aqueous 1N HCl solution was added to the mixture to adjust pH to 3˜4. The resulting mixture was extracted with EtOAc (2×). The organic solution was washed with aq. NaCl, dried over Na2SO4 and concentrated to give 1t (0.34 g).
