Procedure
To a solution of methyl 4(2-oxo-2-phenylethyl)benzoate (1 g, 3.9 mmole) in MeOH (40 mL) was added trimethylorthoformate 10 mL and CSA (50 mg). The reaction mixture was refluxed for 6 h. The mixture was cooled, then Et3N (0.5 mL) was added, and the mixture concentrated. The residue was dissolved in THF and stirred overnight. The reaction was quenched with ACOH (1 mL) and 40 mL pH 7 phosphate buffer. The organic phase was dried (Na2SO4), filtered, and evaporated to yield the title compound 1.1 g.
