Procedure

A solution of Intermediate 151e (89 mg, 0.12 mmol) in THF (0.8 mL) was treated with a 2M solution of dimethylamine in THF (1.2 mL, 2.3 mmol) and the mixture was stirred at 60° C. for 42 h. The cooled solution was concentrated in vacuo, and the residue was partitioned between DCM and water. The phases were separated and the aqueous layer was extracted with DCM (×2). The combined organic phase was washed with brine, dried (Na2SO4) and concentrated in vacuo to a brown glass. The glass was purified by HPLC (Phenomenex Gemini C18 column, 5-95% MeCN in H2O, 0.1% HCO2H) over 25 mins. Concentration of the fractions in vacuo gave a pale yellow glass. The glass was triturated with ether to give a solid that was filtered off to give the title compound as a fawn coloured solid (16 mg, 19%). LCMS (Method 5): Rt 3.68 min, m/z 720.5 [MH+]. 1H NMR (400 MHz, do-DMSO): 0.91 (3H, d, J=6.5 Hz), 1.24 (3H, d, J=6.1 Hz), 1.27 (9H, s), 1.46-1.56 (2H, m), 1.61-1.72 (2H, m), 1.74-1.98 (4H, m), 1.99-2.16 (2H, m), 2.17 (6H, s), 2.32-2.39 (1H, m), 2.86-2.95 (1H, m), 3.13-3.19 (1H, m), 3.29-3.34 (1H, m), 4.56-4.65 (1H, m), 4.79-4.86 (1H, m), 5.52 (1H, t, J=4.4 Hz), 6.32 (1H, s), 6.94-6.99 (1H, m), 7.03-7.12 (3H, m), 7.19 (1H, dd, J=9.9, 2.0 Hz), 7.24-7.41 (5H, m), 7.64 (1H, d, J=10.2 Hz), 7.68-7.70 (1H, m), 8.15 (1H, s), 8.20 (1H, s).
