Procedure

To a solution of 41 (20 mg, 25 μmol) in a mixture of MeOH (1.5 mL) and THF (0.5 mL) was added Pd(OH)2 on carbon (15 mg). A balloon of hydrogen gas was attached for 0.5 h with vigorous stirring. LC/MS indicated that de-protection was complete. The reaction mixture was filtered through Celite, concentrated to a residue, and purified by preparatory HPLC to give 44 (10 mg, 90%) as a mixture of two diastereomers. LCMS m/z 433 (M−OH).
