Procedure

Compound Is was synthesized according to Example 1, using 2-(3,6-dihydro-2H-pyran-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane instead of 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole and 4-chloro-3-iodo-5-phenyl-1-(2-pyrrolidin-1-ylethyl)pyrazolo[3,4-c]pyridazine instead of 4-chloro-3-iodo-1-(2-(4-methylpiperazin-1-yl)ethyl)-5-phenyl-1H-pyrazolo[3,4-c]pyridazine in Step 8.
