Procedure

Trifluoroacetic acid (1 ml) was added under cooling in an ice bath to the compound (10 mg) obtained in Example 70. The mixture was stirred for 2 hr. A saturated aqueous sodium hydrogencarbonate solution was then added to the reaction solution. The mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate. The solvent was then removed by distillation. N,N-dimethylformamide (2 ml) was added to the residue to prepare a solution. Potassium carbonate (lO mg) and 3,3-diphenylpropyl bromide (4 mg) were then added to the solution. The mixture was stirred at room temperature overnight. Water was added to the reaction solution. The mixture was then extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate. The solvent was then removed by distillation. The residue was purified by preparative TLC (hexane:ethyl acetate=1:1) to give the title compound (10 mg).
