実験手順
2-{(3R,6R)-3-(2,3-Dihydro-1H-inden-2-yl)-6-[(1S)-1-methylpropyl]-2,5-dioxo-1-piperazinyl}-2-(4,6-dimethyl-3-pyridinyl)-N-{2-[(phenylmethyl)oxy]phenyl}acetamide (intermediate 3) (3.30 g) was dissolved in ethanol (75 ml) and hydrogenated over palladium on charcoal (wet 10% Pd, 0.50 g) for 20 hours. The catalyst was removed by filtration and washed with dichloromethane. The combined filtrate and washings were evaporated in vacuo. The residue was applied to a 90 g Biotage column and eluted with ethyl acetate. The required fractions were combined and evaporated in vacuo to give 2-{(3R,6R)-3-(2,3-dihydro-1H-inden-2-yl)-6-[(1S)-1-methylpropyl]-2,5-dioxo-1-piperazinyl}-2-(4,6-dimethyl-3-pyridinyl)-N-(2-hydroxyphenyl)acetamide (2.43 g, 87%) as a pale yellow solid.
