Procedure
A solution of the product of step d (217 mg, 0.36 mmol) in trifluoroacetic acid was stirred at room temperature for 16 h. The trifluoroacetic acid was removed in vacuum, the residue was dissolved in chloroform (15 ml) and the solvent was evaporated to afford the triflouoroacetic acid salt. 1H NMR (300 MHz, d6-DMSO) 9.91 (1H, s), 8.52 (1H, d), 7.96 (1H, d), 7.63 (1H, d), 7.45-7.27 (5H, m), 5.00 (2H, br s), 2.93 (2H, m), 2.17 (3H, s), 1.96 (3H, br s), 1.71-1.54 (12H, m), 1.31 (2H, m). Found: C, 62.33; H, 5.73; N, 6.27%. C34H36F3N3O7 requires: C, 62.28; H, 5.53; N, 6.41%.
