실험 절차

A solution of F1 (1.5 eq), F2 (1 eq) and NaHCO3 (2.5 eq) in a mixture of CH3CN and H2O (20:1) was heated at reflux for 12 hrs and then the MeCN was removed under reduced pressure. The resulting residue was diluted with DCM, washed with 1N HCl solution (2×) and then with brine; dried (Na2SO4), filtered and concentrated under reduced pressure. The resulting residue was purified by Biotage system eluting with EtOAc/petrol ether to obtain the desired compound. MS (ES) C24H19ClFN3O3 requires: 451, found: 452 (M+H)+. 1H NMR (400 MHz, DMSOd6) δ: 11.92 (1H, br. S), 7.91 (1H, dd, J=6.2, 1.9 Hz), 7.78-7.71 (1H, m), 7.54 (1H, t, J=9.0 Hz), 7.17-7.11 (1H, m), 7.07-7.04 (1H, m), 6.62-6.57 (1H, m), 6.56-6.20 (2H, m), 4.75 (2H, br. S), 4.46 (2H, br. S), 3.81-3.72 (6H, m).
