Versuchsvorschrift

To a solution of Intermediate 176b (0.10 mmol) and morpholine (17.4 mg, 0.200 mmol) in DCM (3 mL) was added sodium triacetoxyborohydride (31.8 mg, 0.15 mmol) and the resulting yellow solution stirred at RT for 1 h. Water (3 mL) was added and the mixture shaken. The aqueous was extracted with DCM (3 mL), then the combined organics passed through a hydrophobic frit and concentrated in vacuo to leave a vivid yellow gum. Flash chromatography (silica 12 g, 3.5-4.5% (2M NH3 in MeOH) in DCM) gave a vivid yellow gum (70 mg). Prep HPLC (Gemini C18, 25-75% MeCN in water, 0.1% HCO2H, 20 min) and concentration of the desired fractions removed the MeCN. The aqueous was extracted with DCM (3×15 mL), then the combined organics passed through a hydrophobic frit and concentrated in vacuo to leave a glassy orange solid (43.7 mg). Prep HPLC (Gemini C18, 25-50% MeCN in water, 20 min) and concentration of the desired fractions removed the MeCN. The aqueous was extracted with DCM (3×5 mL), then the combined organics passed through a hydrophobic fit and concentrated in vacuo to leave the title compound as a white solid (25.4 mg, 35%). LCMS (Method 5): Rt 3.61 min, m/z 718.6 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.91 (3H, d, J=6.3 Hz), 1.27 (9H, s), 1.47-1.55 (2H, m), 1.63-1.71 (2H, m), 1.76-1.95 (4H, m), 2.00-2.16 (2H, m), 2.37 (4H, t, J=4.3 Hz), 2.90 (1H, ddd, J=12.1, 9.0, 3.9 Hz), 3.16 (1H, dt, J=12.2, 4.3 Hz), 3.29-3.34 (1H, m, obscured by water signal), 3.50 (2H, s), 3.56 (4H, t, J=4.5 Hz), 4.81 (1H, td, J=8.6, 5.6 Hz), 5.51 (1H, t, J=4.3 Hz), 6.34 (1H, s), 7.09 (1H, d, J=8.6 Hz), 7.19 (1H, dd, J=9.9, 2.2 Hz), 7.25-7.37 (4H, m), 7.43 (2H, d, J=8.7 Hz), 7.45 (2H, d, J=8.7 Hz), 7.64 (1H, dd, J=9.8, 0.8 Hz), 7.69 (1H, dd, J=2.2, 0.9 Hz), 8.08 (1H, s).
