Participants

Reaction Steps

The title compound can be synthesized from 4-ethynylcinnoline and N-(3-cyclopropyl-4-((4-methylpiperazin-1-yl)methyl)phenyl)-3-iodo-4-methylbenzamide in a manner similar to that described for Example 1 (nitro reduction performed in a manner similar to that described for Example 10; 0.25M in MeOH/10% AcOH). 4-ethynylcinnoline is prepared from 4-bromocinnoline and ethynyltrimethylsilane according to the 2 steps procedure described in Example 1.
