Reaction Steps

To a solution of 47 (400 mg, 0.568 mmol) in toluene (10 mL) was added TFA (0.874 mL, 11.35 mmol) and the reaction mixture was stirred at RT overnight. The mixture was concentrated to dryness and the residue was purified by Gilson Reverse Phase HPLC (Aquasil C18, elient a linear gradient of 35% MeOH in water to 95% MeOH in water with 0.05% of formic acid, 60 min run) to afford 48 as a white solid, (305 mg, 65% yield) as the TFA salt. MS (m/z): 605.3 (M+H).
