Reaction Steps

A suspension of 2-(3-methoxyquinolin-6-yl)-2-methylpropanoic acid (92 mg, 375 μmol), DIEA (66 μl, 375 μmol), and o-(7-azabenzotriazol-1-yl)-n,n,n′,n-tetramethyl uronium hexafluorophosphate (143 mg, 375 μmol) in DMF was stirred for 2 h at 23° C. To the solution was added 1-(6-phenylpyridazin-3-yl)hydrazine (70 mg, 375 μmol) and stirred for 72 h at 23° C. Reaction partitioned between 9:1 CHCl3/IPA (25 mL) and 1M NaOH (5 mL). Organic dried over MgSO4 the concentrated to a solid from toluene under reduced pressure. Solid triturated with ACN (2 mL) and collected by filtration. 2-(3-methoxyquinolin-6-yl)-2-methyl-N′-(6-phenylpyridazin-3-yl)propanehydrazide isolated as a white solid. MS (ESI pos. ion) m/z: 414 (MH+). Calc'd exact mass for C24H23N5O2: 413.
