Procedure

A mixture of ethyl 2-(11-fluoro-2-(2-(4-fluorophenyl)-3-(methylcarbamoyl)-6-(N-methylmethylsulfonamido)benzofuran-5-yl)-6H-pyrido[2′,3′:5,6][1,3]oxazino[3,4-a]indol-12-yl)-2-hydroxyacetate (233 mg, 0.325 mmol) and lithium hydroxide (54.5 mg, 2.276 mmol) in THF (1 ml), water (0.5 ml) and MeOH (0.5 ml) was stirred at room temperature over night, then concentrated under vacuum. The resulting residue was purified using EP column (30 mm×250 mm), 60% IPA/CO2. This resulted in 128 mg (57.2%) of 2-(11-fluoro-2-(2-(4-fluorophenyl) -3-(methylcarbamoyl)-6-(N-methylmethylsulfonamido)benzofuran-5-yl)-6H-pyrido[2′,3′:5,6][1,3]oxazino[3,4-a]indol-12-yl)-2-hydroxyacetic acid (Compound 207) as a white solid. LC-MS (ES, m/z) C34H26F2N4O8S: 688. Found: 689 [M+H]+.
