Procedure

To a solution of (S)-3-[4-(3,4-Dichloro-benzyloxy)-phenyl]-2-oxo-1,2,3,5,7,8-hexahydro-4-oxa-1,6-diaza-anthracene-6,7-dicarboxylic acid 6-tert-butyl ester (1 mmol) in methanol was added Pd/C (0.2 mmol). The mixture was hydrogenated using balloon for 2-4 h. The mixture was passed through a pad of celite and the filtrate was evaporated to furnish (S)-3-(4-Hydroxy-phenyl)-2-oxo-1,2,3,5,7,8-hexahydro-4-oxa-1,6-diaza-anthracene-6,7-dicarboxylic acid 6-tert-butyl ester. This ester was converted to (S)-7-[(S)-2-(4′-Cyano-biphenyl-4-yl)-1-methoxycarbonyl-ethylcarbamoyl]-3-(4-hydroxy-phenyl)-2-oxo-1,2,3,5,7,8-hexahydro-4-oxa-1,6-diaza-anthracene-6-carboxylic acid tert-butyl ester using the general procedure A. LC-MS (m/z): 704.
