Reference Object Property with JSON.Net when property has special characters

I am using JSON.Net to update an object within an XML File. This works great! However, I need to update a property that has some special charecters in it and I can't find any information out there on how to do this with JSON.Net.

XML

<ProfileSettings>{
  "Name": "Default",
  "Status": "New",
  "DeploymentVariants": {
    "SPSite": {
      "Signature": "SPSite",
      "Type": "SPSite",
      "Label": "SharePoint Site",
      "Source": "Solution",
      "DefaultValue": "http://google.com",
      "Value": "http://google.com"
    },
    "Process/Participant[@Name=\"Manager\"]&gt;User": {
      "Signature": "Process/Participant[@Name=\"Manager\"]&gt;User",
      "Type": "SPUser",
      "Label": "User for swim lane Manager",
      "Source": "Swimlane",
      "DefaultValue": "John Smith",
      "Value": "John Smith"
    }
  },
  "DeploymentScripts": {},
  "SPList": "mySPList"
}</DeploymentProfile>

In order to update the DefaultValue in the SPSite Object, I can use JSON.Net like so:

dynamic fromSolution = JsonConvert.DeserializeObject(profileObject);
fromSolution.DeploymentVariants.SPSite.DefaultValue = txtSPSite.Text;

However, this won't be true if I'm trying to access the Process/Participant[@Name=\"Manager\"]>User object. How can I access a property when it's got special characters like this one?

fromSolution.DeploymentVariants.Process.DefaultValue did not work and obviously including special charecters within that will just result in runtime errors.
