실험 절차

To a solution of the intermediate from example 8 step H (65 mg, 0.122 mmol) in DMF (2 mL) was added HOAt (25 mg, 0.184 mmol), amino tetrazole(32 mg, 0.36 mmol), DIEA (64 μL, 0.37 mmol) and EDC (36 mg, 0.184 mmol). The reaction was stirred at 50° C. for 18 hours. The reaction was diluted with ethyl acetate and washed with 1N HCl and saturated NaCl solution. The organic layer was dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The residue was purified on the Gilson reverse phase HPLC to give the title compound. 1H NMR (DMSO, 500 MHz): 9.12 (s, 1H), 8.4 (dd, J=2.0, 9.1 Hz, 2H), 8.18 (d, J=6.6 Hz, 1H), 8.03 (d, J=1.9 Hz, 1H), 7.83 (dd, J=1.9, 8.3 Hz, 1H), 7.73 (d, J=8.5 Hz, 1H), 7.53 (s, 1H), 7.24 (d, J=8.2 Hz, 1H), 7.24 (d, J=8.2 Hz, 1H), 5.91 (s, 2H), 3.96 (bm, 1H), 1.83 (d, J=12.3 Hz, 2H), 1.48 (m, 3H), 1.28 (m, 2H), 0.98 (m, 1H), 0.82 (s, 9H). LC-MS=2.71 min; (M+H)=596.2.
