실험 절차

TBAF (1M in THF, 350 μL, 0.35 mmol) was added to a solution of Intermediate 22c (258 mg, 0.35 mmol) in THF (5.0 mL) at 0° C. The reaction was stirred for 1 h then partitioned between EtOAc and water. The aqueous layer was then extracted with EtOAc (3×). The combined organic layers were washed with brine, dried (MgSO4), filtered and evaporated in vacuo. The residue was purified by FCC, using 0-10% MeOH in DCM, to give the title compound as an off-white solid (150 mg, 75%). LCMS (Method 1): Rt 4.11 min, m/z 580 [MH+]. 1H NMR (400 MHz, d4-MeOD): 1.30 (9H, s), 1.42 (3H, d, J 6.9), 1.45 (3H, d, J 6.9), 1.88-2.16 (3H, m), 2.20-2.30 (1H, m), 3.51 (1H, sept, J 6.9), 4.90 (1H, dd, J 8.9, 5.6), 5.45 (1H, t, J 4.1), 6.33 (1H, s), 6.84 (1H, ddd, J 8.3, 2.6, 0.8), 6.88-6.94 (2H, m), 7.19-7.26 (2H, m), 7.26-7.33 (4H, m), 7.61 (1H, d, J 10.0), 8.01 (1H, s).
