Procedure

1,1-Dimethylethyl N-((4′-hydroxy-2′-oxo-6′-phenyl-spiro[cyclopentane-1,1′-naphthalen]-3′-yl)carbonyl)glycinate (115 mg, 257 μmol) was dissolved in TFA (2 mL) at ambient temperature. The reaction was stirred for 30 minutes and was then concentrated to give an oil, dissolved in ether, concentrated again to give an amorphous solid, precipitated with ether, filtered, washed with ether, and dried in a vacuum oven to give the title compound (21 mg) as a white solid. MS (m/z)=392 (M+H)+. Calculated for the C23H21NO5 391.14.
