How to get Response Data and parse it to HTTP Header Manager in JMeter

I have run Login sampler and I get the result like this

[Login Sampler Result Data][1]

Here, I want to take

"access_token":"91kLM68tdMBoDFRURArvdmwYgWV9Nr2sHYDwivTM"

and save the "91kLM68tdMBoDFRURArvdmwYgWV9Nr2sHYDwivTM" to a variable, then parse that to HTTP Header Manager here where I want to parse the variable

I am using JMeter version 2.13

Help me please.
