Procedure
A mixture of 52.6 mg (0.069 mmol) of [2-[5-(1,1-dimethyl-2-oxo-2-pyrrolidin-1-ylethyl)-2-(3,5-dimethylphenyl)-1H-indol-3-yl]ethyl]-[4-(4-methanesulfonylaminophenyl)butyl]carbamic acid benzyl ester (from Step 1), 25 mg of 20% palladium hydroxide on carbon, 2.5 mL of ethanol, 2.5 mL of ethyl acetate, and 0.010 mL of glacial acetic acid was shaken with hydrogen (approx. 45 psig) in a pressure vessel for 1.8 hours. The catalyst was removed by filtration through Celite, and the filtrate was concentrated in vacuo. The residue was purified by preparative TLC on 4 Analtech tapered silica gel GF plates (developed in 92.5:7.5:0.75 CH2Cl2-MeOH-concd. NH4OH; product band extracted with the same solvent) yielded 38.4 mg (88%) of cream-colored, stiff foam; homogeneous by TLC in in 92.5:7.5:0.75 CH2Cl2-MeOH-concd. NH4OH. 500 MHz 1H NMR (CDCl3) was consistent with the assigned structure. Mass spectrum (ESI): m/e 629.6 (M+H)+.
