Procedure
The compound (0.30 g, 0.56 mmol) obtained in step C was dissolved in dichloromethane (10 ml), trifluoroacetic acid (1.36 ml) was added, and the mixture was stirred at room temperature overnight. The reaction mixture was concentrated under reduced pressure, water was added, and the mixture was extracted with dichloromethane. The organic layer was dried over anhydrous magnesium sulfate, and the insoluble material was filtered off, and the solution was concentrated under reduced pressure. The obtained oil was purified by silica gel column chromatography (methanol-dichloromethane) to give the title compound (0.32 g) as a colorless amorphous solid. This was directly used for the next step.
