Linux create command with double quotes

Hi there,

I'm trying to dynamically create this string in a variable so that I can then run "eval" on it and run the command remotely on another Linux VM.

ssh oracle@10.41.22.69 "md5sum /data/oracle/dpdump/onegeo/ONEGEO20171214.DMP | awk '{ print \$1 }'"

I can get the string working until the "awk" part and then no matter what I try, I keep getting errors when trying to properly create the rest of the string with single quotes.  The double and single quotes in the string are all required.  

I tried this but it didn't work, what am I missing?
md5command='ssh oracle@10.41.22.69 "md5sum /data/oracle/dpdump/onegeo/'$DMPfilename' | awk '\'{ print \$1 }\''

Any help would be appreciated!!

Thanks,
