实验过程

The mixture of the above obtained methyl[(4Z)-4-[1-(benzylamino)-2-chloroethylidene]-1-(2-chlorophenyl)-5-oxo-4,5-dihydro-1H-pyrazol-3-yl]acetate (Compound of Formula (XIII), 0.32 g), morpholine (1 eq.) and DIPEA (1 eq.) was stirred at room temperature in toluene (3 mL) under nitrogen for 0.5 h at 90° C. Additional 0.5 eq. of morpholine wad added to push reaction to completion. The solvent was removed in vacuo. The resulting brown residue was proved to be the pure methyl[(4Z)-4-[1-(benzylamino)-2-morpholin-4-ylethylidene]-1-(2-chlorophenyl)-5-oxo-4,5-dihydro-1H-pyrazol-3-yl]acetate (0.37 g). Yield 98%. MS (ESI+): 483.9; MS (ESI−): 481.8.
