Reaction Steps

To a solution of Intermediate 92d (240 mg, 0.300 mmol) and TBAF (1M in THF, 0.400 mL, 0.400 mmol) in THF (3 mL) was stirred at RT for 1 h. Water was added and the mixture extracted with DCM (4×20 mL). The combined organics were dried and concentrated in vacuo. The residue was purified by FCC, using 0-14% MeOH in DCM, to give the title compound as an off-white powder after freeze-drying (154 mg, 81%). LCMS (Method 5): Rt 4.01 min, m/z 635.3 [MH+]. 1H NMR (400 MHz, d6-DMSO): 1.27 (9H, s), 1.68-1.79 (1H, m), 1.79-1.97 (2H, m), 1.98-2.14 (3H, m), 2.36 (3H, s), 2.40-2.48 (1H, m), 3.23-3.30 (1H, m), 3.41-3.64 (5H, m), 4.71 (1H, t, J 5.3), 4.77-4.85 (1H, m), 5.51 (1H, br t, J 4.4), 6.33 (1H, s), 7.03-7.10 (2H, m), 7.25-7.40 (8H, m), 7.53 (1H, d, J 9.9), 7.82 (1H, d, J 1.8), 8.03 (1H, s).
