Reaction Steps

The title compound was prepared (as described above for the preparation of Example 2) from 435 mg (0.91 mmol) of Intermediate 45 (as the TFA salt) and 200 mg (0.91 mmol) of Intermediate 29 to yield 125 mg of Example 27 as a beige glassy solid: TLC (DCM/MeOH (4:1): Rf=0.50; 1H NMR (DMSO-d6, 400 MHz) δ11.29 (d, 1H, J=8.8), 7.88 (m, 2H), 7.70 (d, 2H, 8.8), 7.48 (m, 3H), 7.09 (d, 2H, J=8.0), 6.85 (d, 2H, J=8.8), 6.78 (d, 2H, J=8.0), 5.46 (s, 1H), 4.62 (septuplet, 1H, J=6.4), 4.12 (t, 2H, J=6.4), 4.0 (m, 1H), 3.14 (m, 2H), 2.87 (t, 2H; J=6.4), 2.70 (dd, 1H, J=13.2, 9.6), 2.31 (s, 3H), 1.61 (s, 3H), 1.21 (d, 6H, J=6.4); low resolution MS (ES+)m/e 569 (MH+).
