How to pass escape character \" in JSON request to connect rest

In pega, while converting to JSON request we are getting this below

Actual:

eventBody : {“countryCode”:“DEU”,“duration”:“0”}

Expected :

eventBody : {"cultureCode": "en-GB"}

Tried ReplaceAll() function as well, Not working as expected

Please help.
