Hello .
You can use the Partition Wizard boot CD to Move/Resize the left side of the Extended into the unallocated space, this snip below will give you an idea of the process and be sure to post back with any further questions you may have and to keep us informed.
As good and reliable a program as Partition Wizard is, I would not trust the installed version for the operation you need, use the boot CD as suggested and be sure to post back with any further questions you may have and to keep us informed.

First download the Partition Wizard Bootable Disk (PWBD) ISO file to the desktop, be sure to get the PWBD and not the installed version; scroll down to see the download link for the Bootable CD ISO file at this link below.

Then use ImgBurn to burn the ISO to a CD, at no greater than 4x speed with a verify; it was designed for use and works best from a CD rather than a DVD;
then boot the created CD to make the changes, it doesn't take any input from the user to setup, just relax and let it load.
