Procedure

To the compound 6 (225 mg), a solution of 25% trifluoroacetic acid in dichloromethane (6 mL) was added. The reaction mixture was stirred at room temperature for one hour. The reaction mixture was concentrated and the residue was added by 1N sodium hydroxide and then extracted with dichloromethane. The extract was washed with saturated brine, dried over anhydrous sodium sulfate and then concentrated. The obtained residue was purified by silica gel column chromatography (dichloromethane:methanol:28% ammonia water=80:10:1) to obtain the title compound (92 mg) having the following physical properties.
