Reaction Steps

4-{[6-(3-Bromo-propoxy)-biphenyl-3-yl]-hydrazono}-5-(3,4-dimethoxy-phenyl)-2,4-dihydro-pyrazol-3-one (s) and Cs2CO3 were dissolved in 1 mL (2-hydoxy)ethylmethyl amine and the resulting soultion was heated to 50° C. for one hour. The solvent was evaporated and the residue was purified by silica gel chromatography eluent: 10% methanol/DCM) to afford 15 mg 5-(3,4-dimethoxy-phenyl)-4-[(6-{3-[(2-hydroxy-ethyl)-methyl-amino]-propoxy}-biphenyl-3-yl)-hydrazono]-2,4-dihydro-pyrazol-3-one (compound 120): HPLC (Rt): 5.525 minutes; m/e: 531.24, MS (ES+): 532.2.
