Reaction Steps

Compound In was synthesized according to Example 1 Step 8, except 2-(4-chloro-3-iodo-5-phenyl-1H-pyrazolo[3,4-c]pyridazin-1-yl)-1-(pyrrolidin-1-yl)ethanone was used instead of 4-chloro-3-iodo-1-(2-(4-methylpiperazin-1-yl)ethyl)-5-phenyl-1H-pyrazolo[3,4-c]pyridazine and 2-(cyclopent-1-en-1-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane was used instead of 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole.
