실험 절차

117 mg (0.19 mmol) of the product obtained in step c) were dissolved in 5 ml of dichloromethane and stirred for 3 hours with 1 ml of trifluoroacetic acid under an inert gas atmosphere at room temperature. The solvents were removed in vacuo, and the residue was dissolved in acetic acid and again evaporated to dryness. This procedure was repeated once. The resinous residue was triturated with diethyl ether. After filtration 90 mg of a colourless amorphous powder were obtained.
