実験手順

A mixture of 125b (114 mg, 0.20 mmol) and lithium hydroxide (120 mg, 5.0 mmol) in i-propanol/THF/water (2:2:1, 10 mL) was stirred at 35° C. for 30 mins. The mixture was concentrated under reduced pressure and the residue was diluted with water (5 mL). The resulting mixture was extracted with dichloromethane three times. The combined organic layer was then concentrated under reduced pressure and the resulting residue was purified by reverse-phase prep-HPLC to afford 125 (52 mg, 49%). MS-ESI: [M+H]+ 530.9. 1H NMR (500 MHz, DMSO-d6) δ 9.25 (s, 1H), 8.57 (d, J=5.0 Hz, 1H), 8.53 (d, J=3.0 Hz, 1H), 8.25 (d, J=2.5 Hz, 1H), 7.90 (d, J=1.0 Hz, 1H), 7.78 (dd, J=1.0, 13.0 Hz, 1H), 7.61 (d, J=2.0 Hz, 1H), 7.50 (d, J=5.0 Hz, 1H), 6.64 (d, J=1.5 Hz, 1H), 4.92 (bs, 1H), 4.40 (d, J=7.0 Hz, 2H), 3.60 (s, 3H), 2.22 (s, 3H), 1.39 (s, 9H).
