I take it that file1 is multiple lines?

Something like this (untested) works as a brute force approach:

	echo "FILE2START" | cat file1 - file2 | awk '
	    /FILE2START/ { infile2 = 1
			   next
			 }
			 {
			    if (infile2) {
				for (i in tokens)
				    if ($0 ~ i)
					next
				print $0
			    } else
				tokens[$1] = 1
			  }'
	
Hopefully file1 isn't too large.
