Procedure

To a solution of acid 42 (76 mg, 0.266 mmol) and HOBt (40 mg, 0.30 mmol) was added amine 9 (100 mg, 0.29 mmol) and the mixture was stirred at room temperature for 5 min. EDC (62 mg, 0.32 mmol) was added and combined mixture was stirred for additional 48 hours. Additional 42 (38 mg, 0.133 mmol) and EDC (31 mg, 0.16 mmol) were added and the reaction mixture was stirred for a further 24 hours. Again additional 42 (38 mg, 0.133 mmol) and EDC (31 mg, 0.16 mmol) were added and the reaction mixture was stirred for 24 hours more then partitioned between EtOAc and NaHCO3 solution. The organic phase was washed with brine, dried over anhydrous Na2SO4 then filtered and concentrated. The residue was purified by preparative HPLC to afford tert-butyl 4-(3-(3-fluoro-4-(2-(1-methyl-1H-imidazol-2-yl)thieno[3,2-b]pyridin-7-yloxy)phenylamino)-3-oxopropanamido)piperidine-1-carboxylate 42a (20 mg, 13% yield) as a white solid. This material was dissolved in a solution of TFA/DCM (1 mL/2 mL), stirred for 20 min and concentrated. The residue was purified by preparative HPLC (column Aquasil C-18, gradient, MeOH 60% to MeOH 95% in water) to afford the title compound 43 as a tris-trifluoroacetate salt (31 mg, 99%), white solid. 1H NMR (DMSO-d6) δ (ppm): 10.49 (s, 1H), 8.55 (d, 1H), 8.49 (bs, 1H), 8.27 (d, 1H), 8.00 (s, 1H), 7.86 (dd, 1H), 7.55 (s, 1H), 7.49 (t, 1H), 7.39 (dd, 2H), 7.26 (s, 1H), 6.74 (d, 2H), 4.00 (s, 2H), 3.83 (m, 1H), 3.24 (m, 2H), 3.00 (m, 2H), 1.92 (m, 2H), 1.56 (m, 2H). MS (m/z): 509.1 (M+H).
