Reaction Steps

A solution of EXAMPLE 66B in 50% trifluoroacetic acid and dichloromethane mixture was stirred at ambient temperature for 2 hours. The solvents were evaporated and the residue was purified on a reverse phase HPLC using a gradient of 20-80% acetonitrile in water containing 10 mM ammonium acetate. 1H NMR (500 MHz, dimethylsulfoxide-d6) δ 11.61 (s, 1H), 8.52 (bs, 1H), 8.49 (d, 1H), 7.98 (d, 1H), 7.78 (d, 1H), 7.54 (d, 1H), 7.46 (s, 1H), 7.42 (s, 1H), 7.34 (d, 2H), 7.04 (m, 3H), 6.65 (dd, 1H), 6.34 (s, 1H), 6.21 (d, 1H), 3.89 (d, 1H), 3.76 (d, 1H), 3.55-3.46 (m, 2H), 3.40-3.35 (m, 4H), 3.04 (m, 4H), 2.91 (t, 1H), 2.73 (s, 2H), 2.20-2.12 (m, 6H), 1.95 (s, 2H), 1.38 (t, 2H), 0.92 (s, 6H).
