LiOH.H2O (0.379 g, 9.03 mmol) was added to a stirred solution of phenylmethyl 5-methyl-2-[(phenylmethyl)oxy]benzoate (may be prepared as described in Description 8; 1.0 g, 3.01 mmol) in a 3:1 mixture of THF:H2O (40 ml). The mixture was refluxed for 12 h and then diluted with ethyl acetate (50 ml). 10% aqueous HCl was added to the mixture to adjust the pH to 2. The organic phase was isolated, washed with brine, dried over MgSO4, and concentrated to yield the title compound as a yellow solid. 500 mg.
