Procedure

A stirred solution of the intermediate from Step E (0.8 g, 1.46 mmol) in isopropanol (100 mL) was flushed with nitrogen gas and then palladium (80 mg; 10 wt. % (dry basis) on activated carbon) was added. The reaction flask was then placed under vacuum and then flushed with hydrogen gas (3 cycles). The reaction mixture was then stirred for 2.5 hours and then was flushed with nitrogen gas, filtered and the solvent removed under reduced pressure. To the residue was added a 1:1 mixture of acetic acid/water (1.0 mL) and this mixture was then chromatographed on reverse-phase silica gel (gradient elution, 10-50% ACN/water) to provide 60 mg of the title compound (6% yield) as a bis(trifluoroacetate) salt. MS m/z: [M+H+] calc'd for C30H37N3O 456.3; found 456.3. Retention time=3.04 min (10-70% ACN: H2O, reverse phase HPLC).
