Procedure

To an orange solution of Intermediate 176b (0.188 mmol) and N-methyl homopiperazine (43 mg, 0.38 mmol) in DCM (3 mL) was added sodium triacetoxyborohydride (60 mg, 0.28 mmol) and the mixture 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 brown gum. Flash chromatography (silica 12 g, 7-11% [2M NH3 in MeOH] in DCM) gave the title compound as a yellow solid (102 mg, 73%). LCMS (Method 3): Rt 2.84 min, m/z 745 [MH+]. 1H NMR (300 MHz, CDCl3): 0.91 (3H, d, J=6.2 Hz), 1.34 (9H, s), 1.40-1.55 (2H, m), 1.62-1.99 (7H, m), 2.15-2.02-2.14 (2H, m), 2.21-2.30 (1H, m), 2.33 (3H, s), 2.55-2.69 (8H, m), 2.90 (1H, ddd, J=12.1, 9.3, 4.1), 3.04 (1H, dt, J=12.1, 4.2 Hz), 3.23-3.32 (1H, m), 3.58 (2H, s), 5.09 (1H, td, J=8.9, 5.2 Hz), 5.19 (1H, t, J=3.9 Hz), 6.04 (1H, br d, J=8.6 Hz), 6.33 (1H, s), 6.94 (1H, dd, J=9.9, 2.1 Hz), 7.22 (1H, br s), 7.25-7.39 (7H, m), 7.43 (1H, d, J=2.2 Hz), 7.47 (2H, m).
