regular expression for redirect using URLRewriteFillter

[Kydd]

Using a program called URLRewrite on our Tomcat server I'm trying to create the following redirect:
From:

http://www.ourdomain.com/product2.jsp?path=-1|1751&id=1404

to:

http://www.ourdomain.com/ProductDisplay?id=4046

I've created this rule:
<rule>
<from>/product2\.jsp?path=-1|1751&amp;id=1404</from>
<to type="redirect">/ProductDisplay?id=4046</to>
</rule>

Look at the resules of the log below. Apparently, the pipe symbol (|) is being concatenated and parsed into the redirect. I've tried to escape the pipe in the "from" rule above but that doesn't work. Any suggestions?
