Procedure

To a solution of 0.41 g (0.89 mmol) of 1G in 2 mL of dichloromethane was added 2 mL of trifluoroacetic acid. The resulting solution was allowed to stir at room temperature for 90 minutes and concentrated under reduced pressure. The residue was purified by silica gel flash column chromatography using 20% methanol in ethyl acetate to give 0.29 g (0.64 mmol, 69%) of 1H as a colorless thick gum (M+Na, 357).
