How to write one revritcond for multiple revriterule?

Question

htaccess

Hello!
I am writing a rule for a web server. I understand this poorly, I read the documentation, but have not yet reached the desired answer.
The task is as follows: to open another page at a certain address.
The page on which the content is located has the following form amp/produkcziya/pryamaya-uf-pechat/uf-pechat-na-polistirole/index.html.
Page to redirect to amp/produkcziya/pryamaya-uf-pechat/na-polistirole/.
My attempts look like this:

Ст. 1 - RewriteCond %{REQUEST_URI} ^/amp/.*
Ст. 2 - RewriteRule ^amp/uslugi/frezerovka/kompozita/$ amp/uslugi/frezerovka/frezerovka-kompozita/index.html [L]

As I understand it: Art. 1, we define a pattern and say that after the domain, the string must begin with amp, and any number of arbitrary characters can follow.
Further in Art. 2 we substitute catch the request and replace it with content from another page.
If I add Art. 3, which must also match the specified pattern, then nothing works. And I went this way. I copy St. 1 then add the following reregistration. And so 20 times. That's how it works. I understand that the solution is not elegant, but so far, there is not enough knowledge for the best option.
Please tell me if you know how.
