Regexp: How to find and replace brackets around numbers in notepad-CodePudding

I would like to do a regex replace operation in notepad

here is the test string:

td{2}(i,j),
td{3}(i,j),
td{4}(i,j),

And I would like to end up with this:

td(2,i,j),
td(3,i,j),
td(4,i,j),

I can find the string, but I don't know how to write the replacement string.

\{\d{1}\}\(

I tried the above expression with (.)$ to find the number

\{\d{1}\}\(

and this for the replacement string but it didn't work

 \($1,

How can I get the results I want?

\{(\d)}(\()

Replace with $2$1,. Also, see the
