To a solution of the product of Example 83 (20 mg, 0.43 mmol) in THF (2 mL) was added LiOH (40 mg, 1.67 mmol) dissolved in H2O (1 mL). The reaction mixture was stirred 1 h at 23° and then neutralized with 1 M HCl, extracted with EtOAc (5 mL) and the layers were separated. The organic layer was washed with H2O, satd. aq NaCl, and dried (MgSO4). The solution was filtered and evaporated to give the title compound [4,8-bis-(2-chloro-phenyl)-7-oxo-7,8-dihydro-pyrido[2,3-d]pyrimidin-2-ylamino]-acetic acid. LC MS (m/e)=441 (MH+). Rt=1.85 min
