Procedure

Compound 16.7 (460 mg, 0.763 mmol) was dissolved in 8 mL anhydrous DMF, treated with 2,6-lutidine (0.443 mL, 3.81 mmol) and TMSBr (1.5 mL, 11.4 mmol). The mixture was stirred at 80° C. for 4 h and quenched with MeOH. The mixture was concentrated under reduced pressure and the residue was subjected to reverse phase HPLC to yield product 16.8 (60 mg, 14.4% yield).
