sed not taking variable value

Hi All,
Could you please help me, why sed is not able to take variable value when I try to replace using sed.
I want to replace 2nd column (time) and keeping intact others.

Code:
cur="09:30"
CODE="VL"
new="09:35"

sed s/'\(.*def.monitor."${CODE}".qStart.*\)"${cur}"\(.*read\)/\1"${new}"\2'/g $FILE > /tmp/newFile

From
Code:
abcxx.def.monitor.VL.qStart         09:30               read

TO
Code:
abcxx.def.monitor.VL.qStart         09:35               read

Mod Comment Please use CODE tags correctly (i.e. not enclosing a (sub)total text) as required by forum rules!

NAME
impressive-gettransitions - Generate Impressive info scripts for LaTeX presentations SYNOPSIS
impressive-gettransitions FILE.tex DESCRIPTION
A simple script to produce a .info file for use with Impressive, using special comments in a LaTeX/Beamer file. FILE.tex is a file to be parsed into .info file. For each /fullpath/blah.tex /fullpath/blah.pdf.info gets produced. SYNTAX
In the LaTeX document, impressive-gettransitions counts the pages to determine the PDF slide number of each one. The simpler page changes are automatically detected, that is: egin{frame} and: pause Other, more elaborated page changes must be noted with a %O comment: item<1-> Foo item<2-> Bar %O The transition to apply can be specified in a %O comment: egin{frame} %O SlideUp OPERATION
When the .info file corresponding to the LaTeX document already exist, impressive-gettransitions does not clear it, but only adds the transitions if finds to it. Thus, if you modified your document in a way that requires to completely replace the transitions, manually clear the PageProps section of the .info file. This can be done by running the following sed command: sed -i -e "/^PageProps = {/,/^}/d" FILE.info SEE ALSO
