Procedure
To a flask containing 66.14A (75 mg, 230 μmol) in MeOH (2 mL) was added sulfuric acid (0.61 μL, 11 μmol), and the mixture was stirred at reflux overnight. The reaction was concentrated and then purified by silica gel chromatography (0 to 30% EtOAc/Hexanes) to provide 66.14B (77.0 mg, 98% yield).
