Reaction Steps

The product of Example 205 (0.030 g, 0.0703 mmol) in acetonitrile (2 ml) was treated with the product of Example 461A (0.018 g, 0.077 mmol) and triethylamine (0.011 ml, 0.077 mmol), stirred at 60° C. for 20 hours and cooled to about 25° C. The solvent was evaporated under reduced pressure, and the residue was purified by reverse phase preparative HPLC on a Waters Symmetry C8 column (25 mm×100 mm, 7 μm particle size) using a gradient of 10% to 100% acetonitrile/10 mM ammonium acetate in water over 8 minutes (10 minutes run time) at a flow rate of 40 mL/min give the title compound (7 mg, 16%). 1H NMR (300 MHz, DMSO-d6) δ 0.99 (d, J=6.25 Hz, 6 H) 1.59 (m, 2 H) 1.67 (m, 2 H) 1.87 (m, 4 H) 2.09 (d, J=8.46 Hz, 1 H) 3.60 (s, 3 H) 4.26 (dd, J=8.64, 3.86 Hz, 1 H) 4.50 (m, 2 H) 7.55 (m, 4 H) 7.73 (d, J=8.82 Hz, 1 H) 8.57 (dd, J=8.09, 1.84 Hz, 1 H) 8.90 (dd, J=4.78, 1.84 Hz, 1 H) 10.53 (s, 1 H) 14.07 (s, 1 H).
