Not able to kill process by “kill -9 “

I want to kill process, which related to rsync.

By entering “ps axu | grep -i lsyncd” I receive information about onw process:

andrej   10690  0.0  0.0  15984  1148 pts/1    S+   16:52   0:00 grep --color=auto -i lsyncd

But when I,m trying to kill it, by using “sudo kill -9 10690” I receive:

 kill: (10690): There is no such process
