Procedure

The title compound 3-(3-((3-aminophenoxy)methyl)phenyl)-6-(1-(benzo[d]thiazol-2-ylcarbamoyl)-1,2,3,4-tetrahydroquinolin-7-yl)picolinic acid (34) was prepared by the following procedure: Trifluoroacetic acid (0.5 mL) was added to a solution of 6-(1-(benzo[d]thiazol-2-ylcarbamoyl)-1,2,3,4-tetrahydroquinolin-7-yl)-3-(3-((3-(tert-butoxycarbonylamino)phenoxy)methyl)phenyl)picolinic acid (34E) (0.016 g, 0.022 mmol) in anhydrous DCM (0.75 mL). The reaction mixture was stirred at rt for 1.5 hours, concentrated under reduced pressure, and the crude material triturated in diethyl ether to provide the desired product 3-(3-((3-aminophenoxy)methyl)phenyl)-6-(1-(benzo[d]thiazol-2-ylcarbamoyl)-1,2,3,4-tetrahydroquinolin-7-yl)picolinic acid (34): 1H NMR (300 MHz, DMSO) δ 8.43 (1H, s, br), 8.08 (1H, d), 7.99 (1H, d), 7.85-7.77 (2H, m), 7.67 (1H, s), 7.55-7.41 (4H, m), 7.37 (1H, t), 7.31 (1H, d), 7.22 (1H, t), 7.12 (1H, t), 6.59-7.50 (2H, m), 6.47 (1H, d), 5.11 (2H, s), 3.97 (2H, t), 2.84 (2H, t), 1.96 (2H, m). MS (ESI(+)) m/z 628.1 (M+H).
