Redirect bash STDOUT to a file within a for loop

I have a bash for loop that looks like this:

for entry in ~/properties/*  
do
  PROP=$(basename "$entry")
  echo $PROP
  my_converter $entry -o $OPATH$PROP.vcl --tf --tf-file=$OPATH$PROP.tf
done

This does most of what I need. I set the OPATH variable before the loop and create a new file with the same name and append a different file extension.

What's missing is to write the output generated by running my_converter into another file with the same name but with a file extension of .info.

Some things I've tried (based on this question):

my_converter $entry -o $OPATH$PROP.vcl --tf --tf-file=$OPATH$PROP.tf >> $OPATH$PROP.info

and creating a new file descriptor with the .info file as the target:

  ...
  do
    exec 3>$entry.info
    PROP=$(basename "$entry")
    echo $PROP
    my_converter $entry -o $OPATH$PROP.vcl --tf --tf-file=$OPATH$PROP.tf 1>3
  ...

And for completeness, I've also tried just doing a regular redirect:

my_converter $entry -o $OPATH$PROP.vcl --tf --tf-file=$OPATH$PROP.tf > $OPATH$PROP.info

I know there's some redirect voodoo I can do to get this working. Any help greatly appreciated.
