trouble in cropping content outside clipping mask



i'm trying to make usual layer from path so I can to move letter without changes caused of clippeing mask. It should look like the 2 screenshot. Rasterizing gives me untransparency which I don't want, so I unbuilt clipping mask(as on the last screenshot) to do the crop but Illustator doesn't let me (the first screenshot)
how to fix it or is ther any other way to achieve my goal?
