Procedure

The product of step G prepared above (152 mg) was dissolved in anhydrous dichloromethane (3.0 mL). Trimethylsilyl bromide (0.5 mL) was added at 0° C. The mixture was stirred during 1 h at this temperature and overnight at room temperature. The solvent was evaporated and 0.2 mL water was added to the residue. 3 mL EtOH was added mixed and evaporated. This step was repeated three times and the residue dried in vacuo. Yields 98 mg 70% of the title derivatives of this first example.
