Procedure

A solution of Example 168C (27.7 mg, 0.027 mmol) in dichloromethane (0.5 mL) was treated with trifluoroacetic acid (0.25 mL) at 25° C. for 2 h. The solvents were evaporated, and the residue was dissolved in dichloromethane, washed with saturated sodium bicarbonate, dried over MgSO4, filtered, and the solvents were evaporated. The crude residue was purified by silica gel chromatography eluting with a gradient of dichloromethane, 100% ethyl acetate, and 95% ethyl acetate/7% methanol to give the title compound (4 mg, 16%). 1H NMR (300 MHz, DMSO-d6) δ ppm 0.81(s, 9H), 1.53(m, 2H), 2.42-2.30(m, 2H), 2.64-2.60(m, 1H), 2.79-2.71(m, 4H), 3.50(s, 3H), 3.54(s, 3H), 3.61(m, 1H), 3.79(d, J=4.04 Hz, 1H), 4.03(m, 4.13(m, 1H), 4.27(m, 1H), 4.57(bs, 1H), 6.17(m, 1H), 6.84(m, 1H), 7.12(m, 1H), 7.21-7.19(m, 7H), 7.27(m, 1H), 7.48(d, J=7.81 Hz, 1H), 7.82(bs, 2H), 7.87-7.86(d, J=7.81 Hz, 2H), 8.62-8.61(d, J=4.39 Hz, 1H).
