Versuchsvorschrift

A 50-mL single-neck round-bottomed flask was charged with 220b (100 mg, 1.0 eq., 0.15 mmol), NaBH4 (30 mg, 5.0 eq., 0.75 mmol), methanol (5 mL), and dichloromethane (5 mL). The mixture was stirred at 0° C. for 10 min and quenched with water (5 mL). It was then filtered and the filtrate was concentrated under reduced pressure. The residue was purified by reverse-phase prep-HPLC to afford the title compound (10 mg, 10%). MS-ESI: [M+H]+ 637.5. 1H NMR (500 MHz, DMSO-d6) δ 8.61 (d, J=2.0 Hz, 1H), 8.44 (s, 1H), 8.24 (d, J=5.0 Hz, 1H), 7.82 (d, J=3.0 Hz, 1H), 7.53 (d, J=2.0 Hz, 1H), 7.39-7.36 (m, 1H), 7.24 (d, J=9.0 Hz, 1H), 6.99 (d, J=5.0 Hz, 1H), 5.55 (s, 1H), 5.36-5.35 (m, 1H), 4.57-4.54 (m, 2H), 4.48-4.40 (m, 6H), 3.92-3.90 (m, 2H), 3.79-3.67 (m, 3H), 3.59 (s, 3H), 3.40-3.37 (m, 2H), 3.09-3.07 (m, 1H), 2.95-2.92 (m, 1H), 2.55-2.51 (m, 2H), 2.38-2.30 (m, 4H), 2.17-2.16 (m, 1H), 1.75-1.74 (m, 2H), 1.68-1.65 (m, 2H), 0.92 (d, J=6.5 Hz, 3H).
