I would like to add a link to an existing pdf that jumps to a coordinate on another page.

I am able to add a rectangle using this code:

PdfContentByte overContent = stamper.GetOverContent(1);
iTextSharp.text.Rectangle rectangle = new Rectangle(10,10,100,100,0);
rectangle.BackgroundColor = BaseColor.BLUE;

How can I do similar to create a link that is clickable?

You are already adding the Rectangle, now you need to add the annotation:

PdfAnnotation annotation = PdfAnnotation.CreateLink(
    stamper.Writer, rectangle, PdfAnnotation.HIGHLIGHT_INVERT,
    new PdfAction("https://itextpdf.com/")
stamper.AddAnnotation(annotation, page);

In this code sample page is the number of the page where you want to add the link and rectangle is the Rectangle object defining the coordinates on that page.
