Procedure

To a solution of Intermediate 176b (0.188 mmol) and piperidine (37.2 μL, 0.38 mmol) in DCM (3 mL), sodium triacetoxyborohydride (59.8 mg, 0.28 mmol) was added. The mixture was stirred at RT for 1 h. Water was added and the mixture extracted with DCM. The combined organics were passed through a phase separator and concentrated to dryness. The resulting residue was purified by RP-HPLC (C18, 18 mL/min, 20-85% MeCN in H2O+0.1% HCO2H) and the relevant fractions combined and concentrated to dryness. The title product was isolated as an off white solid (14 mg). LCMS (Method 5): Rt 3.71 min, m/z 716.6 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.91 (3H, d, J=6.4 Hz), 1.27 (9H, s), 1.36 (2H, m), 1.47 (6H, m), 1.67 (2H, m), 1.76-1.96 (4H, m), 1.98-2.16 (2H, m), 2.33 (4H, m), 2.90 (1H, m), 3.15 (1H, m, obscured by solvent), 3.46 (2H, s, obscured by solvent), 4.81 (1H, m), 5.51 (1H, t, J=4.1 Hz), 6.33 (1H, s), 7.09 (1H, d, J=8.6 Hz), 7.19 (1H, dd, J=10.0, 2.2 Hz), 7.24-7.46 (8H, m), 7.64 (1H, d, J=10.0 Hz), 7.69 (1H, d, J=1.5 Hz), 8.09 (1H, s), 8.17 (1H, s).
