Procedure

1,1-Dimethylethyl N-((6-(2-methylphenyl)-4-hydroxy-1,1-dimethyl-2-oxo-naphthalen-3-yl)carbonyl)glycinate (160 mg, 367 μmol) was dissolved in TFA (2 mL) at ambient temperature. The reaction was stirred for 30 minutes and then concentrated, precipitated with hexanes, filtered, washed with hexanes, and dried in a vacuum oven to give the title compound (57 mg) as a light yellow solid. MS (m/z)=380 (M+H)+. Calculated for C22H21NO5 379.14.
