How do I disconnect from someone who doesn't try enough for our friendship?

I'm having trouble distancing myself from one of my friends, sure she talks to me but usually I have to engage in the convo first. Then when we do talk it's so boring, she's a nice person n' all but I don't really feel like her friend. I'm trying to see this situation from all povs but I'm still concerned about how to approach this. Any suggestions? I'm open to anything.
