実験手順
To a solution of the title compound from Example 2 Step B (1.50 g, 3.79 mmol) in acetonitrile (9.5 mL) was added N-chlorosuccinimide (760 mg, 5.69 mmol), and the resulting mixture was placed in a pre-heated oil bath (90° C.). After 1 h, the reaction mixture was allowed to cool to room temperature, then was diluted with DCM, and the resulting mixture was washed with brine. The organic phase was then concentrated in vacuo. Purification by chromatography on silica gel (0 to 30% EtOAc in hexanes, then 30 to 100% EtOAc in hexanes) provided the title compound: LCMS m/z 429.9 [M+H]+; 1H NMR (500 MHz, CDCl3) δ 12.50 (s, 1H), 8.18 (s, 1H, 8.14 (t, J=8.0 Hz, 1H), 7.99 (d, J=8.0 Hz, 1H), 7.58 (d, J=8.0 Hz, 1H), 7.46 (dd, J=9.0, 3.0 Hz, 1H), 7.25 (dd, J=9.0, 3.0 Hz, 1H), 4.40 (q, J=7.0 Hz, 2H), 1.40 (t, J=7.0 Hz, 3H).
