Trifluoroacetic acid → Trifluoroacetic acid

Participants

Reaction Steps

The product of Example 64B was treated with trifluoroacetic acid (3 mL) in methylene chloride (3 mL) at room temperature for 30 minutes. The solvents were removed under vacuum to provide the title compound as a trifluoroacetic acid salt. 1H NMR (300 MHz, DMSO-D6) δ ppm: 1.37 (d, J=6.99 Hz, 6 H) 3.30 (m, 1 H) 6.65 (d, J=8.46 Hz, 2 H) 6.97 (d, J=8.46 Hz, 1 H) 7.16 (d, J=8.46 Hz, 2 H) 7.30 (m, 2 H) 7.72 (m, 1 H) 7.88 (dd, J=8.46, 1.84 Hz, 1 H) 7.96 (m, 2 H) 8.05 (s, 1 H) 8.92 (s, 1 H) 9.07 (d, J=8.46 Hz, 1 H) 10.37 (s, 1 H) 11.82 (s, 1 H); MS (ESI+) m/z 585, 587 (M+H)+.
