SSH Command on remote server

Question

I'm stuck in a situation,

I run this command on node2

netstat -tlpna|grep `ps aux|grep tnslsnr|grep -v grep|awk '{print $2}'`|head -1

and it works fine and gives me this output

tcp        0      0 10.6.1.22:1521          0.0.0.0:*               LISTEN      2601/tnslsnr 

But when i run this command from clinet machine to node2 it gives me error.

ssh  root@$(pcs status|grep oracle_LR|awk '{print $4}') 'netstat -tulpna $(ps aux|grep -v grep|grep tnslsnr'|awk '{print $2})'

After Following from @steeldiver

I added double quote around awk and it is working

ssh root@$(pcs status|grep oracle_LR|awk '{print $4}') 'netstat -tulpna|grep $(ps aux|grep tnslsnr|grep -v grep|awk "{print \$2}")'|head -1

gives me this output

tcp 0 0 xxx.xxx.xxx.xxx:1525 0.0.0.0:*
LISTEN 2601/tnslsnr

BUT

when i add this line in my script.

$echo "<pre>`ssh root@$(pcs status|grep oracle_LR|awk '{print $4}') 'netstat -tulpna|grep $(ps aux|grep tnslsnr|grep -v grep|awk "{print \$2}")'|head -1`</pre>"

and when i run it gives me this output

grep: oracle: No such file or directory
grep: 2601: No such file or directory
grep: 0.0: No such file or directory
grep: 0.0: No such file or directory
grep: 227812: No such file or directory
grep: 18536: No such file or directory
grep: ?: No such file or directory
grep: Ssl: No such file or directory
grep: Aug27: No such file or directory
grep: 6:16: No such file or directory
grep: LISTENER: No such file or directory

I have been playing around with this but nothing is working
