Redirect URLs with Curly Brackets in it – SEO

I have about 30.000 old urls that need to be redirected
I am using excel to obtain a rewrite rule for each URL

My old URLS are using a Unique Identifier in the query string part
Basically I am trying to redirect

www.mysite.com/dettagli.asp?ID_S={965c1471-b985-45c1-9d7a-9fcede5711ed}

to

www.mysite.com/mynewurl.html

I can map any UID to the new URLS in excel but rewrite rules so far haven’t been successful

I have tried escaping the cury brackets with “” in front of them, no luck

So far I have tried

redirect 301  /dettagli.asp?ID_S={965c1471-b985-45c1-9d7a-9fcede5711ed} 

and

redirect  301  /dettagli.asp?ID_S={965c1471-b985-45c1-9d7a-9fcede5711ed}
