To a solution of the product from Example 138B (0.20 g, 0.28 mmol) and the product from Example 144C (0.11 g, 0.42 mmol) in toluene (2.8 mL) was added TFA (22 μL, 0.28 mmol). The mixture was stirred at 110° C. for 3 hours. To the cooled mixture was added TFA (0.5 mL) and the mixture was stirred for 1 h at rt. The solvent was then removed under reduced pressure and triturated with diethylether and dried to provide 0.31 g of the desired compound as a TFA salt. 1HNMR (DMSO-d6; 400 MHz): δ 9.78 (br s, 2H), 7.84 (d, J=2.71 Hz, 1H), 7.75 (s, 2H), 7.67 (AA′XX′, J=8.34 Hz, 4H), 7.35 (dd, J=9.11, 2.71 Hz, 1H), 7.18 (AA′XX′, J=8.46 Hz, 4H), 6.79 (d, J=9.11 Hz, 1H), 6.53 (s, 2H), 4.79 (app t, J=7.81 Hz, 2H), 3.4-3.2 (m, 4H), 2.44-2.36 (m, 2H), 2.25-1.98 (m, 6H), 1.65-1.45 (m, 6H).
