Procedure

To a solution of the title compound of Step (B) in 1.5 ml of CH3CN, Me3SiCl (34 mg, 0.32 mmol) was added and followed by NaI (48 mg, 0.32 mmol). The mixture was stirred at room temperature for 0.5 hr. Additional Me3SiCl (46 mg, 0.42 mmol) and NaI (63 mg, 0.42 mmol) were added in three portions and the reaction mixture was stirred for additional 1 hr and 45 min. The mixture was then added to 2 ml H2O and 20 ml EtOAc. The organic layer was washed with 1 ml sat. Na2 S2O3, brine, dried and concentrated. The residue was purified by preparative HPLC on an ODS S10 column using 30% solvent A (10% MeOH, 90% H2O, 0.1% TFA) and 70% solvent B (90% MeOH, 10% H2O, 0.1% TFA) to provide the title compound of this Example (7 mg, 23% for two steps) as a white solid, m.p. 98°-106° C. (amorphous).
