If you are asking about the awk command then I don't think so you need not escape anything there, because you have used double quote " so it shouldn't be an issue.
Now coming onto your command, I am pretty sure that could be written in more easy way if you could show us the sample Input_file and expected output too, let us know on same.
Please become accustomed to provide decent context info of your problem.
It is always helpful to support a request with system info like OS and shell, related environment (variables, options), preferred tools, adequate (representative) sample input and desired output data and the logics connecting the two, and, if existent, system (error) messages verbatim, to avoid ambiguities and keep people from guessing.
