Procedure

To a solution of Intermediate 79f (210 mg, 0.260 mmol) in THF (4 mL) at −30° C. was added TBAF (1M in THF, 390 μL, 0.390 mmol) and the mixture was allowed to warm to RT over 1 h. The reaction mixture was applied to an SCX-2 cartridge (10 g) and washed with MeOH. The product was eluted with 2M NH3 in MeOH; concentration in vacuo gave a residue. FCC, using 0-10% [2M NH3 in MeOH] in DCM, and then recrystallisation from boiling EtOAc (˜40 mL) gave the title compound as a white powder (67 mg, 40%). LCMS (Method 5): Rt 4.31 min, m/z 649.1 [MH+]. 1H NMR (400 MHz, d4-MeOH): 1.30 (3H, s), 1.33 (9H, s), 1.71-1.77 (2H, m), 1.84-1.93 (2H, m), 1.95-2.17 (3H, m), 2.25-2.32 (1H, m), 2.41 (3H, s), 3.20-3.28 (2H, m), 3.36-3.45 (2H, m), 4.72-4.92 (1H, m), 5.47 (1H, t, J 4.4), 6.36 (1H, s), 6.88 (1H, d, J 9.3), 7.21-7.40 (8H, m), 7.58 (1H, d, J 9.7), 7.62 (1H, d, J 1.7).
