反応手順
The ethyl ester product from part (e) (1.75 g., 2.63 mmole) is dissolved in methanol (75 ml.) at room temperature under argon. The solution is hydrogenated with 20% palladium hydroxide on carbon catalyst (300 mg.) at room temperature and atmospheric pressure for 3 hours. The reaction is filtered through Celite to remove the catalyst, and the volatiles are evaporated to give 1.7 g. of 1-(S)-6-[(Trifluoroacetyl)amino]-2-[[[(1-amino)pentyl]methoxyphosphinyl]oxy]-1-oxohexyl]-L-proline, ethyl ester.
