Rename specific file extension in directory with match to another file in bash

I have a specific set (all ending with .bam) of downloaded files in a directory /home/cmccabe/Desktop/NGS/API/2-15-2016. What I am trying to do is use a match to $2 in name to rename the downloaded files. To make things a more involved the date of the folder is unique and in the header of name the date of the match exists and is where the match in name is located. I am not sure how to do this or if it is possible. I have tried a sed command with no luck, maybe that isn't the best way. Thank you :).

sed tried:

for f in /home/cmccabe/Desktop/NGS/API/2-12-2016/*.bam ; do
  bname=$(basename $f)
  cmd=$(sed -n "/$f/,/[0-9]{1,2}-[0-9]{1,2}-20[0-9]{2}/{s/\(.*\.bam\) \(.*\)/mv \1 \2/p}" /home/cmccabe/Desktop/NGS/panels/name.txt)
  echo "$cmd"
done
sed: -e expression #1, char 4: extra characters after command 

try:

sed -n "/$bname/,/[0-9]{1,2}-[0-9]{1,2}-20[0-9]{2}/{s/\(.*\.bam\) \(.*\)/mv \1 \2/p}"
