Procedure

A solution of Intermediate 94d (243 mg, 0.29 mmol) and TBAF (1M in THF, 0.53 mL, 0.53 mmol) in THF (3.5 mL) was stirred at RT for 45 min, then diluted with water and extracted with DCM (3×20 mL). The combined organics were dried and concentrated in vacuo. The residue was purified by FCC, using 0-7.5% (2M NH3 in MeOH) in DCM, to give the title compound as a white powder after freeze-drying (135 mg, 58%). LCMS (Method 5): Rt 3.52 min, m/z 664 [MH+]. 1H NMR (400 MHz, d6-DMSO): 1.27 (9H, s), 1.86-1.92 (2H, m), 2.04-2.11 (2H, m), 2.36 (3H, s), 2.48 (2H, q, J 5.8), 2.66 (4H, t, J 4.8), 3.19 (4H, t, J 4.5), 3.55 (2H, q, J 5.8), 4.44 (1H, t, J 5.4), 4.79-4.82 (1H, m), 5.57 (1H, t, J 4.4), 6.32 (1H, s), 7.07 (1H, d, J 8.5), 7.15 (1H, dd, J 9.9, 2.1), 7.32-7.44 (8H, m), 7.60-7.63 (1H, m), 7.68 (1H, d, J 2.0), 8.04 (1H, s).
