Question: I would like to say in German,

So far I have this,

Is *reden* the right verb here? How would you say it?

Answer: 
Your translation works.
Another possibility would be

> 
> Ich würde mich gerne mal mit dir unterhalten
> 
> 
> 

Which is a way to ask for a conversation some time in the future. The “dir“ is used when talking to a friend or close co-worker while it can be exchanged with “Ihnen“ to suit a more formal setting.
Irgendwann würde ich (sehr) gerne mal mit Dir reden.
