Reaction Steps

A stirred suspension of intermediate 14 (Example 21) (0.058 g, 0.076 mmol) in DCM (8 mL) was treated with TFA (0.100 mL) and stirred for 3 h. Solvents were then removed yielding desired product as TFA salt (0.05 g, 99%). 1H NMR (DMSO-d6): δ 1.62-1.70 (m, 2H), 2.01-2.08 (m, 4H), 2.8-2.9 (m, 2H), 3.3-3.6 (m, 2H), 3.45-3.49 (m, 1H), 7.61 (d, J=8.8 Hz, 1H), 7.74 (d, J=8.8 Hz, 2H), 7.81 (t, J=15.7 Hz, J=7.8 Hz, 1H), 7.93 (dd, J=8.8 Hz, J=2.5 Hz, 1H), 8.00 (d, J=7.6 Hz, 1H), 8.05 (d, J=8.9 Hz, 2H), 8.10 (d, J=2.5 Hz, 1H), 8.20-8.32 (m, 3H), 8.65-8.69 (m, 1H), 8.90 (s, 2H), 10.37 (s, 1H), 10.76 (s, 1H), 10.80 (s, 1H).
