実験手順

Sodium hypochlorite (1.408 mL, 0.912 mmol) was added to a stirred, room temperature mixture of tert-butyl 5-(2-(4-fluorophenyl)-6-((hydroxyimino)methyl)-1-oxo-1,2-dihydroisoquinolin-3-yl)pentanoate (100 mg, 0.228 mmol) and 1-fluoro-4-(prop-2-ynyl)benzene (61.2 mg, 0.456 mmol) in dichloromethane (2 mL), and the mixture was stirred at room temperature for overnight. The reaction was checked with LCMS and starting material was all consumed. The mixture was diluted with dichloromethane (10 mL), washed with aqueous sodium hydrogen carbonate (saturated, 1×8 mL), dried (MgSO4), filtered and the solvent was evaporated under reduced pressure. The residue was purified by column chromatography on silica gel, eluting with EtOAc/isohexane=50% to give tert-butyl 5-(6-(5-(4-fluorobenzyl)isoxazol-3-yl)-2-(4-fluorophenyl)-1-oxo-1,2-dihydroisoquinolin-3-yl)pentanoate (102 mg, 0.179 mmol) as a yellow solid.
