실험 절차

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer was charged with 242b (150 mg, 0.29 mmol, 1.0 eq.), NaBH4 (55 mg, 1.46 mmol, 5.0 eq.), and methanol (10 mL). The resulting mixture was stirred at room temperature for 20 min. It was then filtered and the filtrate was concentrated under reduced pressure. The residue was purified by reverse-phase prep-HPLC to afford 242 (100 mg, 66%) as a white solid. MS-ESI: [M+H]+ 514.3. 1H NMR (500 MHz, DMSO-d6) δ 8.47 (d, J=5.5 Hz, 1H), 8.04-8.03 (m, 2H), 7.42 (d, J=2.0 Hz, 1H), 7.30 (d, J=5.0 Hz, 1H), 6.05 (s, 1H), 5.90 (s, 1H), 4.87-4.85 (m, 1H), 4.43-4.35 (m, 2H), 4.18-4.12 (m, 1H), 3.98-3.93 (m, 1H), 3.84-3.78 (m, 2H), 3.59 (s, 3H), 3.58 (s, 3H), 3.06-2.92 (m, 2H), 2.75-2.68 (m, 2H), 2.18 (s, 3H), 1.94-1.92 (m, 2H), 1.79-1.73 (m, 2H).
