Linux command output not getting redirected

Why doesn't the output get redirected in this case. The user doesn't have permission to write in /proc hence the error but why the error isn't going to /dev/null? 

$echo "core_%e.%p" > /proc/sys/kernel/core_pattern 2>&1 > /dev/null

-bash: /proc/sys/kernel/core_pattern: Permission denied

Try with:

echo "core_%e.%p" 2>/dev/null > /proc/sys/kernel/core_pattern 2>&1

that will send stdout and stderr to "core_pattern", if possible, if not, ends without message.

works too:

bash -c 'echo "core_%e.%p" > /proc/sys/kernel/core_pattern' > /dev/null 2>&1
