Reaction Steps

To a suspension of 2-(4-chlorophenyl)acetic acid (1.07 mmole), HOBT (1.07 mmole), and EDCI hydrochloride (1.61 mmole) in DMF (7 mL) were added N-(4-(6-hydrazinylpyridazin-3-yl)phenyl)methanesulfonamide (1.07 mmole) in 10 mL of DMF followed by diisopropylethylamine (3.77 mmole). The resulting mixture was stirred at room temperature for 22 hours and evaporated in vacuo. The desired product N-(4-(6-(2-(2-(4-chlorophenyl)acetyl)hydrazinyl)pyridazin-3-yl)phenyl)methanesulfonamide was precipitated out from water.
