Procedure

Acetone (0.5 mL) was added to a mixture of the product of Example 289 (80 mg, 0.183 mmol) and sodium triacetoxyborohydride (77 mg, 0.366 mmol) in 1,2-dichloroethane (5 mL). The reaction mixture was stirred at room temperature overnight. The mixture was filtered and washed with dichloromethane. The filtrate was concentrated under reduced pressure and purified by preparative HPLC on a Thermoquest, hyperprep HS C18 column (250×21.2 mm., 8 μm particle size) using a gradient of 5% to 75% acetonitrile to ammonium acetate (10 mM) over 20 minutes at a flow rate of 21 mL/min to provide the title compound. MS (ESI+) m/z 479.3 (M+H)+; Rt=1.63 min. 1H-NMR (400 MHz, DMSO-d6) δ 0.96 (d, J=6.6 Hz, 1H), 1.80 (m, 2H), 1.90 (s, 2H), 2.65 (m, 2H), 2.70 (m, 2H), 2.86 (m, 1H), 3.38 (m, 4H), 4.44 (d, J=5.3 Hz, 1H), 5.75 (s, 1H), 6.84 (dd, J=4.8 Hz, J=7.5 Hz, 1H), 7.52 (dd, J=1.9 Hz, J=7.5 Hz, 1H), 7.58 (t, J=50.5 Hz, 1H), 7.73 (t, J=8.8 Hz, 1H), 7.86 (dd, J=5.3 Hz, J=9.0 Hz, 1H), 8.07 (dd, J=1.9 Hz, J=4.7 Hz, 1H).
