实验过程

To a Parr shaker flask was added N-({5-hydroxy-6-(1-methylethyl)-2-[(4′-nitro-2-biphenylyl)methyl]-3-oxo-2,3-dihydro-4-pyridazinyl}carbonyl)glycine (example 89, 65 mg, 0.139 mmol) and palladium on carbon (7.41 mg, 0.070 mmol) in Methanol (10 ml) and Ethyl acetate (2.500 ml) under a nitrogen atmosphere. The mixture was placed on a Parr shaker under 50 psi Hydrogen for 1 hour. The reaction mixture was filtered to remove the palladium on carbon followed by removal of the solvent by rotary evaporation and purification by HPLC chromatography (ODS silica, gradient 10-85% acetonitrile/water (0.1% TFA)) to afford the title compound N-{[2-[(4′-amino-2-biphenylyl)methyl]-5-hydroxy-6-(1-methylethyl)-3-oxo-2,3-dihydro-4-pyridazinyl]carbonyl}glycine (29 mg, 0.063 mmol, 45.3% yield) as a white powder. 1H NMR (400 MHz, DMSO-d6) d ppm 15.86 (s, 1H), 10.11 (t, J=5.56 Hz, 1H), 7.19-7.36 (m, 5 H), 7.05 (d, J=7.07 Hz, 1H), 6.93 (d, J=7.33 Hz, 2H), 5.25 (s, 2H), 4.08 (d, J=5.56 Hz, 2H), 3.16 (sept, J=6.82 Hz, 1H), 1.15 (d, J=6.82 Hz, 6H). MS (ES+) m/e 437 [M+H]+.
