Quote:

It begins in C#m and the chorus ends in B.




Go to the five chord of B first.

That would be an F#.

F#7 is often harmonically superior to the plain jane F# Major.

Sometimes a modulation can happen a bit smoother by doing a "two-ve" transition instead of just the jump to the five chord of the target key.

The two is minor and the five is Major, so that would be C#minor followed by the F#7 -- often done in one bar, two beats for each of the two chords.
