Versuchsvorschrift

To a mixture of 7-(3-{[(3-isopropylphenyl)amino]carbonyl}phenyl)-5,6,7,8-tetrahydro-2,7-naphthyridine-4-carboxylic acid (47 mg, 0.113 mmol), triethylamine (0.047 mL, 0.34 mmol), and catalytic DMAP in 3.0 mL 1,2-dichloroethane at rt was added propylphosphonic anhydride solution (50 wt % in EtOAc, 0.081 mL, 0.136 mmol). After 5 min at rt, 3-amino-1-propanol (0.011 mL, 0.147 mmol) was added and the reaction stirred at rt for 2 hours. The reaction was quenched with aqueous NaHCO3 solution, extracted with EtOAc, the EtOAc layer washed with H2O, aqueous NaHCO3 solution, brine, dried with anhydrous Na2SO4 and rotary evaporated. This material was chromatographed eluting with CHCl3/EtOAc plus 10% MeOH to give the title compound as a light yellow solid (20 mg, 37%). 1H NMR (CDCl3) δ: 8.46 (s, 1H), 8.41 (s, 1H), 8.02 (s, 1H), 7.54 (s, 1H), 7.44-7.51 (m, 2H), 7.19-7.39 (m, 4H), 7.10 (d, J=8.2 Hz, 1H), 7.03 (d, J=7.6 Hz, 1H), 6.81 (t, J=5.6 Hz, 1H), 4.45 (s, 2H), 3.78 (t, J=5.4 Hz, 2H), 3.53-3.65 (m, 4H), 3.17 (t, J=5.6 Hz, 2H), 2.86-2.97 (m, 1H), 1.77-1.86 (m, 2H), 1.27 (d, J=6.7 Hz, 6H)
