Procedure

A solution of Intermediate 66d (207 mg, 0.253 mmol) and TBAF (1M in THF, 0.303 mL, 0.303 mmol) in THF (4 mL) was stirred at RT for 2.25 h. The mixture was diluted with water and extracted with DCM (4×15 mL). The combined organic extracts were dried and concentrated in vacuo. The residue was purified by FCC, using 0-15% MeOH in DCM, to give the product. This was further purified by HPLC (C18 X-select column, 30-98% MeCN in H2O, 0.1% formic acid) to give the title compound as an off-white powder after freeze-drying (114 mg, 68%). LCMS (Method 5): Rt 4.29 min, m/z 663.3 [MH+]. 1H NMR (400 MHz, d6-DMSO): 1.27 (9H, s), 1.38-1.51 (4H, m), 1.57-1.68 (1H, m), 1.72-1.97 (4H, m), 1.99-2.16 (2H, m), 2.36 (3H, s), 2.85-2.95 (2H, m), 3.30-3.52 (4H, m, under water signal), 4.38 (1H, s), 4.77-4.85 (1H, m), 5.55 (1H, t, J 4.3), 6.32 (1H, s), 7.09 (1H, d, J 8.6), 7.16 (1H, dd, J 9.9, 2.2), 7.26-7.40 (8H, m), 7.61 (1H, d, J 9.9), 7.65 (1H, d, J 1.4), 8.06 (1H, s).
