PROCEDURE

实验过程

To a 100 mL flask containing (S)-2-(4-cyano-2,6-difluorobenzoylamino)-3-[4-(1,3,6-trimethyl-2,4-dioxo-1,2,3,4-tetrahydro-pyrimidin-5-yl)phenyl]propionic acid propyl ester (524 mg, 1.0 mmol) dissolved in n-propanol (20 mL) purged with nitrogen was added palladium on carbon (10%, 106 mg). The reaction was sealed, degassed with three exposures to nitrogen and house vacuum, and then exposed to a balloon of hydrogen overnight. The reaction was diluted with EA, degassed again, and exposed to hydrogen overnight. The reaction was filtered through celite, concentrated and purified by HPLC yielding the title compound (204 mg, 19%). ES(+)-LRMS m/e calcd. for C54H57F4N7O10 (M+H)+ 1041, obsd 1041.
