Reaction Steps

The product from Example 257c (mg, 0.462 mmol) was dissolved in a 1:1 mixture of TFA in CH2Cl2 and stirred at room temperature for 2 hrs. The solvent was removed under vacuum and the crude oil was purified by HPLC with TFA providing the product as a trifluoroacetic acid salt (16 mg, 6%). 1H NMR (300 MHz, DMSO-d6) δ ppm: 1.32 (t, J=6.99 Hz, 6 H), 3.18-3.33 (m, 1 H), 6.82-6.91 (m, 4 H), 6.99 (d, J=9.19 Hz, 1 H), 7.39 (d, J=4.04 Hz, 1 H), 7.61 (dd, J=8.82, 2.57 Hz, 1 H), 7.81 (d, J=8.46 Hz, 1 H), 7.86 (d, J=4.04 Hz, 1 H), 7.99 (d, J=2.57 Hz, 1 H), 8.81 (s, 1 H), 8.91 (d, J=8.09 Hz, 1 H), 10.45 (s, 1 H); MS (ESI+) m/z 575 (M+TFA+H)+; (ESI−) m/z 573 (M+TFA−H)−.
