HCID 6422Trifluoroacetic acidSolvent

Procedure

Compound 135 (6.18 g, 16.7 mmol) was dissolved in trifluoroacetic acid (17 mL), followed by stirring at room temperature for 1 hour. The reaction mixture was concentrated under reduced pressure, ethyl acetate and a saturated aqueous solution of sodium hydrogencarbonate were added to the residue, and the organic layer was separated. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was purified through silica gel column chromatography (hexane:ethyl acetate=1:4) to afford the entitled Compound 136 (4.39 g, 97%).
